Add linting for TypeScript configuration files

[mcmire]

It is easy for the TypeScript files to be misconfigured due to requirements that aren't obvious.

At the project level, the following should hold true:

• In tsconfig.json, references should cover all public workspace packages, and all paths should point to valid files and end with /tsconfig.json [note: this is not the case now but we can add it for consistency with the next rule]
• In tsconfig.build.json, references should match references in tsconfig.json except that all paths should end with /tsconfig.build.json and point to valid files.

For each public workspace package, the following should hold true:

• tsconfig.json should be present and:
  • extends should be "../../tsconfig.packages.json"
  • compilerOptions.baseUrl should be "./"
  • all paths in references (if present) should point to valid files and end with /tsconfig.json [note: this is not the case now but we can add it for consistency with the next rule]
  • include should include "../../types" and "./src"
• tsconfig.build.json should be present and:
  • extends should be "../../tsconfig.packages.build.json"
  • compilerOptions.baseUrl should be "./"
  • compilerOptions.dist should be "./dist"
  • compilerOptions.rootDir should be "./src"
  • all paths in references (if present) should match those in tsconfig.json except they should end with /tsconfig.build.json and should be valid files
  • include should include "../../types" and "./src"

We may be able to auto-generate project references from Yarn workspaces. See various solutions posted here: https://github.com/microsoft/TypeScript/issues/25376
