fix(amplify-cli-core): use build script for overrides (#13858)

Updated the TypeScript compilation of overrides so that it doesn't require `node_modules/.bin/tsc`.
Instead, it simply relies on the `build` script to execute `tsc`.
This is more flexible and can support alternative setups w/ hoisting (e.g. via Yarn workspaces).

This is an override corollary fix to #11854, which is for custom resources.
