This integrates TypeScript into the compile cache by caching the transpilation (either type-stripping or transforming) output in addition to the V8 code cache that's generated from the transpilation output. Locally this speeds up loading with type stripping of `benchmark/fixtures/strip-types-benchmark.ts` by ~65% and loading with type transforms of `fixtures/transform-types-benchmark.ts` by ~128%. When comparing loading .ts and loading pre-transpiled .js on-disk with the compile cache enabled, previously .ts loaded 46% slower with type-stripping and 66% slower with transforms compared to loading .js files directly. After this patch, .ts loads 12% slower with type-stripping and 22% slower with transforms compared to .js. (Note that the numbers are based on microbenchmark fixtures and do not necessarily represent real-world workloads, though with bigger real-world files, the speed up should be more significant).
