perf(@angular/build): avoid loading compiler-cli and typescript in js transform worker

Previously, `OxcLinker` imported `ConsoleLogger` and `LogLevel` directly from
`@angular/compiler-cli`. Even though `@angular/compiler-cli/linker` is an isolated,
lightweight runtime (depending only on `semver` and `convert-source-map`), resolving
the main `@angular/compiler-cli` entry point (`bundles/index.js`) eagerly evaluated
the full `ngtsc` compiler toolchain and required the 10 MB `typescript.js` bundle at
the top level.

As a result, every worker isolate in the JavaScript transformer pool unnecessarily loaded
TypeScript and 50+ compiler modules upon bootstrap, incurring ~150 ms of startup CPU latency
and allocating ~12 MB of heap per worker thread.
