feat(cli, router, metro, asset): add basePath support (#23911)

# Why

- Add the ability to export websites for hosting from a custom path.
This is required for GitHub pages.
- Resolve ENG-9193
- Resolve https://github.com/expo/expo/issues/20562
- Resolve https://github.com/expo/router/issues/165

issues, forums posts, or feature requests.

# How

- Add `expo.experiments.basePath` which can be used during `npx expo
export` to modify how assets are referenced.
- Set the `publicPath` in Metro to output as expected.
- Add custom asset writing for web to support stripping the unused
prefix.

- It's unclear if this should also apply to native, and if we should
have platform-specific variations.
- Update Expo Router to support automatically adjusting paths to support
basePath in production builds.

[config][cli] Remove classic manifest types (#24054)

[lint] Upgrade to Prettier v3, typescript-eslint to v6 (#23544)

Why
---
Prettier 3 is out. Add support for it with this linter config.

**Note for reviewer:** the first commit is the one with the actual
changes. The rest of this PR are changes to get the linter passing
(mostly autofix).

How
---
Update eslint-config-prettier and eslint-plugin-prettier. To address
deprecation warnings, also update typescript-eslint/parser and
typescript-eslint/eslint-plugin.
Because of an update to typescript-eslint/parser, we need to suppress
deprecation warnings (documented in a comment).

Regenerated test snapshots. Due to the upgraded dependencies, typecasts
and optional chaining are now auto-fixable by lint. This converts
warnings into autofixes.

Test Plan
---
`yarn test` in the linter config. Run `expotools check --all --fix-lint
--no-build --no-test --no-uniformity-check` to try this config on the
whole repo.

feat(metro-config, cli): CSS support for Metro web (#21941)

# Why

This PR moves the CSS support from Expo Router over to
`expo/metro-config` behind a beta flag. This is because we need deeper
integration with Expo CLI and Metro in order to emit static CSS files in
production bundles. CSS is required for media queries -> rehydration.

- Related: https://github.com/expo/router/pull/397
https://github.com/expo/router/pull/223

# How

Instead of a babel transformer, we now use a custom "transformer" which
gives us the ability to add extra metadata to a Metro module on export.
This means we can pass the raw and processed CSS for writing to disk.

The development version of CSS still uses script injection via
JavaScript, meaning static rendering cannot currently be tested in
development.

CSS Modules are implemented (web-only currently) using lightningcss. The
export is generated to work with React Native for web. Consider the
following block:

```js
export default { ...StyleSheet.create({ container: { $$css: true, _: 'hashed-container-id' } }) }
```

CSS Variables are not currently hashed, enabling the user to define
variables in a global CSS file and access them in CSS Modules (subject
to change in order to support native). CSS variables are accessible from
the default export as strings: `styles['--color'] === '--color'`.


## Docs

I've chosen to document in the versioned metro doc instead of the
unversioned guide, this seems like a reasonable spot given the highly
experimental nature of this feature.
