feat: various fixes

[mdonnalley]

• Support .mts and .cts file extensions (Fixes Support mts and cts file extensions which typescript nightly builds support using compilerOptions.module = "nodenext" #362)

  • QA for .cts:
    • git clone https://github.com/oclif/hello-world
    • yarn link @oclif/core
    • rename hello.ts to hello.cts
    • bin/dev.js hello oclif --from me
    • yarn tsc && bin/run.js hello oclif --from me
  • QA for .mts:
    • git clone https://github.com/oclif/hello-world-esm
    • yarn link @oclif/core
    • rename hello.ts to hello.mts
    • bin/dev.js hello oclif --from me
    • yarn tsc && bin/run.js hello oclif --from me

• Support baseUrl for configuring source directory (Fixes Missing tsconfig.json:compilerOptions.rootDir makes dev-mode load commands from ./dist/ #716)

  • QA:
    • git clone https://github.com/oclif/hello-world
    • yarn link @oclif/core
    • remove rootDir from tsconfig and replace with baseUrl: "./src"
    • bin/dev.js hello oclif --from me

• Bump ejs and other deps (Closes fix(deps): bump ejs and @types/ejs #821, Closes build(ejs): bump ejs v to 3.1.9 #790)

• Parallelize flag and arg caching

• Add a Cache class for caching the root plugin. This is better than the previous solution, which relied on the root plugin being processed by tsPath, which won't happen if the root plugin does not contain any commands

  • QA: passing esm-cjs interoperability tests are sufficient for QA'ing this
