In #14567 I claimed that the underlying allocation is reused. And it
was. At the time I've submitted a PR I was using `.filter_map(|x| x)`,
which got flagged by clippy as something that could be simplified to
`.flatten()` - that however broke the allocation reuse promise.

Thus, this PR goes back to using `filter_map` and additionally in debug
builds it performs checks for allocation reuse. With .flatten in place,
a bunch of unit test fail on that branch, so the checks do work.

- Fixes #14418. Originally broken by #13946

# Background
In https://github.com/zed-industries/zed/issues/14408 we received a
repro for "Replace all" being slow, even after the work I did
https://github.com/zed-industries/zed/pull/13654. Admittedly #13654 was
a pretty straightforward change.
Under the profiler it turned out that we're spending *10 seconds* in
`memmove` on main thread. Ugh. Not great. The direct ancestor of the
memmove call was
https://github.com/zed-industries/zed/blob/66f0c390a88f5aa16d21047a8982a5888fa0f816/crates/editor/src/display_map/tab_map.rs#L108-L119

What?

# Accidental O(n^2)
We have a bunch of `consolidate_*_edits` functions which take a list of
Fold/Tab/Inlay/Wrap edits and merge consecutive edits if their ranges
overlap/are next to one another. The loop usually goes as follows:
```
while ix < edits.len() {
    let (prev_edits, next_edits) = edits.split_at_mut(ix);
    let prev_edit = prev_edits.last_mut().unwrap();
    let edit = &next_edits[0];
    if PREV_EDIT_CAN_BE_MERGED_WITH_CURRENT_ONE {
        MERGE_EDITS(prev_edit, edit);
        edits.remove(ix); // !!
    } else {
        ix += 1;
    }
}
```
The problem is the call to `.remove` - it has to shift all of the
consecutive elements in the `edits` vector! Thus, when processing the
edits from the original repro (where consolidation shrinks the edit list
from 210k entries to 30k), we mostly spend time moving entries in memory
around.

Thus, the original repro isn't really an issue with replace_all; it's
just that replace_all is one of the few tools available to the end user
that can apply large # of edits in a single transaction.

# Solution
In this PR I address the issue by rewriting the loop in a way that does
not throw items away via `.remove`. Instead, `Iterator::scan` is used,
which lets us achieve the same logic without having the pitfalls of
`.remove`s.
Crucially, **this code does not allocate a new backing buffer for
edits** (see [this article for
rationale](https://blog.polybdenum.com/2024/01/17/identifying-the-collect-vec-memory-leak-footgun.html));
with `vec.into_iter().scan().filter_map().collect()` we still use the
same underlying buffer as the one that's passed into `consolidate_*`
functions. In development I verified that by checking whether the
pointers to backing storage of a Vec are the same before and after the
consolidation.

### After

The remaining lag is (I think) lies in `TextSummary` calculation and not
the consolidation itself. Thus, for the purposes of scoping this PR,
I'll tackle it separately.

Release Notes:

- Significantly improved performance of applying large quantities of
concurrent edits (e.g. when running "Replace all").

Turns out that the existing CI step for Nightly did create the licenses
and they have been baked into X86 builds ever since, because our
builders are stateful.

On ARM machines, the licenses wouldn't exist in the binary because we
called `script/generate-licenses` too late in `scripts/bundle-linux`,
after the binary had been created.

This removes the duplication and generates the licenses once, before the
binary is created.

Fixes #14302.

Release Notes:

- Fixed "View Dependency Licenses" (or `zed: open licenses`) crashing on
Linux ARM machines.
([#14302](https://github.com/zed-industries/zed/issues/14302)

Felt the link we were using for menu items that open a browser page was
not the best. That one is most typically used for attachments within
scope, as opposed to opening external links. Noticed that via the
"Copilot Settings" menu, which also felt like it could have a bit more
descriptive label. Also reduced the size of the rendered icon in this
component.

This PR adds support for displaying file icons in tabs.

The `tabs.file_icons` setting controls whether the icons are displayed:

```json
{
  "tabs": {
    "file_icons": false
  }
}
```

This setting defaults to `true`.

Release Notes:

- Added file icons to buffer tabs
([#12138](https://github.com/zed-industries/zed/issues/12138)).
- If desired, these icons can be removed using `"tabs": { "file_icons":
false }`.

This PR extends the extensions page with support for upselling built-in
Zed features when certain keywords are searched for.

This should help inform users about features that Zed has out-of-the-box
when they go looking for them as extensions.

For example, when someone searches "vim":

<img width="1341" alt="Screenshot 2024-07-15 at 4 58 44 PM"
src="https://github.com/user-attachments/assets/b256d07a-559a-43c2-b491-3eca5bff436e">

Here are more examples of what the upsells can look like:

src="https://github.com/user-attachments/assets/1f453132-ac14-4884-afc4-7c12db47ad1d">

Release Notes:

- Added banners for built-in Zed features when corresponding keywords
are used in the extension search.

Provide a current, broken state as an experimental way to browse
diagnostics.
The diagnostics are grouped by lines and reduced into a block that, in
case of multiple diagnostics per line, could be toggled back and forth
to show more diagnostics on the line.
Use `grouped_diagnostics::Deploy` to show the panel.

Issues remaining:
* panic on warnings toggle due to incorrect excerpt manipulation
* badly styled blocks
* no key bindings to navigate between blocks and toggle them
* overall odd usability gains for certain groups of people

Due to all above, the thing is feature-gated and not exposed to regular
people.

Do not require the `prettier` dependency name to be in package.json's
[dev]Dependencies, instead just checking the `node_modules` contents.

([12731](https://github.com/zed-industries/zed/issues/12731)

Currently deno lsp only works because deno have a workaround when it
detects deno.json it gets activated, but without a deno.json it won't
work
With this change now it works correctly regardless of a deno.json
presence, it only require enable:true:


```json
{
  "lsp": {
    "deno": {
      "settings": {
        "deno": {
          "enable": true
        }
      }
    }
  }
}
```


Release Notes:

- Improved initial Deno set-up to enable it without explicit deno.json present in the file system
