[compiler] Switch to esbuild (#31963)
This migrates the compiler's bundler to esbuild instead of rollup.
Unlike React, our bundling use cases are far simpler since the majority
of our packages are meant to be run on node. Rollup was adding
considerable build time overhead whereas esbuild remains fast and has
all the functionality we need out of the box.


### Before
```
time yarn workspaces run build
yarn workspaces v1.22.22

> babel-plugin-react-compiler
yarn run v1.22.22
$ rimraf dist && rollup --config --bundleConfigAsCjs

src/index.ts → dist/index.js...
(!) Circular dependencies
# ...
created dist/index.js in 15.5s
  Done in 16.45s.

> eslint-plugin-react-compiler
yarn run v1.22.22
$ rimraf dist && rollup --config --bundleConfigAsCjs

src/index.ts → dist/index.js...
(!) Circular dependencies
# ...
created dist/index.js in 9.1s
  Done in 10.11s.

> make-read-only-util
yarn run v1.22.22
warning package.json: No license field
$ tsc
  Done in 1.81s.

> react-compiler-healthcheck
yarn run v1.22.22
$ rimraf dist && rollup --config --bundleConfigAsCjs

src/index.ts → dist/index.js...
(!) Circular dependencies
# ...
created dist/index.js in 8.7s
  Done in 10.43s.

> react-compiler-runtime
yarn run v1.22.22
$ rimraf dist && rollup --config --bundleConfigAsCjs

src/index.ts → dist/index.js...
(!) src/index.ts (1:0): Module level directives cause errors when bundled, "use no memo" in "src/index.ts" was ignored.
# ...
created dist/index.js in 1.1s
  Done in 1.82s.

> snap
yarn run v1.22.22
$ rimraf dist && concurrently -n snap,runtime "tsc --build" "yarn --silent workspace react-compiler-runtime build --silent"
$ rimraf dist && rollup --config --bundleConfigAsCjs --silent
[runtime] yarn --silent workspace react-compiler-runtime build --silent exited with code 0
[snap] tsc --build exited with code 0
  Done in 5.73s.
  Done in 47.30s.

### After

```
time yarn workspaces run build
