build: update @biomejs/biome to 2.x (microsoft#26617)

## Summary

- Update `@biomejs/biome` from `~1.9.x` to `~2.4.5` across all packages
in both the client and build-tools release groups
- Remove temporary `@biomejs/biome` pnpm overrides from both root and
build-tools `package.json` that were used to stage the upgrade
- Remove syncpack workarounds: the biome ignore rule in
`build-tools/syncpack.config.cjs` and the biome entry from version
compatibility workarounds in `syncpack.config.cjs`
- Apply biome 2.x formatting changes: removal of unused generic type
parameters in `exposedInternalUtilityTypes.ts`, `typeUtils.ts`, and
`latestValueTypes.ts`
- Collateral lockfile changes: `acorn` 8.15.0 -> 8.16.0 and `acorn-walk`
8.3.4 -> 8.3.5 resolved as part of the lockfile update
