A new ESM loader equivalent of 'ts-node/register/transpile-only'

Continuing the discussion from #1007.

CommonJS has the file shortcut ts-node/register/transpile-only for installing the TypeScript loader without type checking. An ESM loader which has the equivalent functionality should be created and exposed to the end user.

ts-node/esm.mjs

Line 7 in ce7c323

export const {resolve, getFormat, transformSource} = esm.registerAndCreateEsmHooks()

The code from esm.mjs can be duplicated in a new file, but with the transpileOnly flag set:

export const {resolve, getFormat, transformSource} = esm.registerAndCreateEsmHooks({transpileOnly: true})

What should the loader filename look like? There is ts-node/esm.mjs, should it be ts-node/esm/transpile-only.mjs?

[cspotcode]

ts-node/esm/transpile-only.mjs makes sense to me. A user does node --loader ts-node/esm/transpile-only ./foo.ts

Resolved with #1102
