Introduce dynamic module

- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes fix#25439
- [x] There are tests for these changes
Because MSVC uses a different calling conventions for functions that
return non-POD values, we need to use the new exposed wrapper function
so that `GetScriptPrivate` can be handled correctly on Windows.
Use `asynch` instead of `r#async`
<!-- Please describe your changes on the following line: -->
This is a vestige of the transition from 2015 to 2018 edition Rust.
`async` was added as a keyword in 2018 edition Rust, so `cargo fix`
changed the variable name here to `r#async`.

Implement WebGPU ErrorScopes
<!-- Please describe your changes on the following line: -->
This PR covers the following-
1. update wgpu-core (Rustify `RenderPipelineDescriptor`)
2. Add initial implementation of `pushErrorScope` and `popErrorScope`.
3. Use existing `BGL` if an equivalent already exists.
A brief explanation of the ErrorScope Implementation-
1. We store `HashMap<u64, ErrorScopeInfo>` in `GPUDevice`. `ErrorScopeInfo` is a new struct used to store all necessary info for an ErrorScope.
2. We simultaneously store `Vec<u64>` to keep track of the ErrorScope hierarchy. `next_scope_id` is used to get the `scope_id` for a new Scope.
3. We send the `scope_id` of top-level scope to the server in the message for an operation. The server performs the operation and sends back the scope_id with the result message (only if a scope_id was sent from the client. Otherwise no message is sent.).
4. We store a `HashMap<WebGPUDevice, Dom<GPUDevice>>` in `GlobalScope` to access them from `ScriptThread`.
5. While creating a `GPUDevice` we send the `PipelineId` of the pipeline it was created in so that when the server send the response, we can access the device from the GlobalScope of that Pipeline.
6. We generate the relevant `GPUError` in `GlobalScope`(if required) can call the necessary fn in `GPUDevice`.
This implementation is pretty rough and not complete at all. Broadly the following cases aren't handled at the moment-
1. ErrorFilter is not checked when an error is captured.
2. We don't propagate an error to enclosing scope if a scope did not capture it.
3. `UncapturedErrorEvents` is not implemented.
As for Equivalent BGLs we now store `Vec<(Vec<wgt::BindGroupLayoutEntry>, Dom<GPUBindGroupLayout>)>` in `GPUDevice` and compare `Vec<wgt::BindGroupLayoutEntry>` for new BGL with the existing ones and return one if it is found. Otherwise a new one is created and an entry added to the `Vec`.

Web developers can use `Dynamic Import` in a classic script; thus, we
need to save the script's private reference so that we can reuse it when
we're going to fetch a dynamic import module for a classic script.
Besides, because it's possible to use different executing context for a
dynamic import module (like `dynamic-import/string-compilation-other-document.html` WPT test),
we can't initialize a module owner at the timing of `SetScriptPrivate`;
thus, if the private module script doesn't hold an owner, we'll use a
DynamicImport owner for it.
Make gstreamer packaging explicit
This change aligns Windows and macOS in terms of loading an explicit set of included plugins when initializing gstreamer. It also creates a single source of truth - the set of expected plugins is generated in a build script by the same python code that is used for packaging, so it should be impossible for platforms relying on this system to get out of sync.
Fixes#27293
Use `Rc` instead of cloning the `DOMString`
<!-- Please describe your changes on the following line: -->
I changed the `text` field of `ScriptOrigin` from a `DOMString` to an `Rc<DOMString>`. Then I updated all the related code to work with an `Rc`.

This is a vestige of the transition from 2015 to 2018 edition Rust.
`async` was added as a keyword in 2018 edition Rust, so `cargo fix`
