```
javascript, typescript: Inject GLSL and WGSL syntax in comment-labeled template literals (#55341)

Extends the existing ECMAScript comment-label injection system to
support GLSL and WGSL shader languages inside JS/TS strings and template
literals.

The pattern `/* language */` before a string is already used for `html`,
`sql`, `graphql`, and `css`. This adds the same support for two shader
languages commonly embedded as strings in WebGL/WebGPU code:

/>

/>

Syntax highlighting activates when the corresponding extension is
installed:
- GLSL: the built-in `glsl` extension
- WGSL: the community extension
[`wgsl-wesl-zed`](https://github.com/lucascompython/wgsl-wesl-zed)
(language name `WGSL/WESL`)

Both `/*glsl*/` and `/* glsl */` forms are accepted (same behavior as
the existing patterns).

Release Notes:

- Added `/*glsl*/` and `/*wgsl*/` comment-label syntax injection for
JavaScript and TypeScript template literals
```
