Use the `TraverseCtx::generate_uid` method introduced in #3395 to fix
some of the TS namespace test cases.
But... I honestly have no idea what I'm doing here!
I am running up against a combination of 3 different areas where I know
very little:
1. I am unfamiliar with `Semantic`.
2. I am unfamiliar with Oxc's conventions for writing transforms.
3. I don't "speak" Typescript!
This PR should not be merged as is. I'm pretty sure it's wrong. I've
done it mostly just to test out `generate_uid`.
In particular:
1. Is `SymbolFlags::FunctionScopedVariable` the right flags to use in
all cases here?
2. `generate_uid` creates a symbol, and registers a binding for it in
the scope tree. So if there are any branches in this logic where `name`
doesn't actually get used after `generate_uid` is called, then it's not
right.
3. Identifiers which are added to AST should also have corresponding
`ReferenceId`s created for them (but I imagine this is also missing in
many other places in the transformer).
On point 2: We could split up `generate_uid` into 2 functions. One
function would find a valid UID name *but not register a binding for
it*. If you want to actually use that name, you'd call a 2nd function to
generate the binding. Would that be a better API?
Could someone help me out to progress this please?
(Sorry my lack of knowledge is a bit useless here. I will learn all
these things in time, but just trying to be honest about where I'm at
right now. I'm sure I could figure it out myself, but it would take me
hours, whereas others will probably look at it and know what to do in
about 5 mins.)
Move `BabelOptions` to Transformer. The `output.json` is a standard babel configuration. We can reuse BabelOptions to read [babel.config.json](https://babeljs.io/docs/configuration#babelconfigjson) or our configuration(maybe oxc.config.json)
The current `from_babel_options` implementation is copied from the `transform_options` in `test_case.rs`, which I'll completely reimplement next
If submodules are outdated, it'll panic with the following message
```
Repository is outdated, please run `just submodules` to update it.
```
For us maintainers, we'll need the env `UPDATE_SNAPSHOT` to force an update.
Sliced off from #3152.
Re-implement `transform-react-display-name` using bottom-up lookup
provided by `Traverse` trait.
This fixes the 1 remaining failing test case for this plugin (see
#2937).
`Traverse` is not complete yet (see #3182), so this is also not ready to
merge yet.
It seems like we need to rebuild the scopes and symbols while
traversing. We can't utilize the scopes and symbols built by semantic
because they are immutable.
The remaining test cases will perform better with a scope
implementation, and while we can implement them without the scope, it
still requires us to do what the scope did.

`codegen` relies on the modifier to decide whether to print or not. For
example, if declare is present, nothing will be printed if typescript is
not enabled.
We may need to solve this problem in a way that doesn't rely on
modifers.
