fix(js): set compilerOptions correctly when loading .ts that targets ESM (#27862)

Browse Source 
When we load `.ts` files and the closest `package.json` specifies
`"type": "module"`, then the file may error upon loading. This happens
because we're not setting `compilerOptions` correctly when registering
`ts-node/esm`-- in fact there is no way to pass options through this
hook.

This PR sets defaults on `TS_NODE_COMPILER_OPTIONS` such that the
`module` and `moduleResolution` are correct values for ESM. It also
works for CJS since both `module` and `moduleResolution` check the
closest `package.json` to determine the format.
