Allow overriding TypeScript compilerHost

[jscheid]

Feature request

I've managed to get Yarn PnP working together with TypeScript, but initially only with ignoreBuildErrors: true. TypeScript validation can be made to work by using ts-pnp but requires a nasty hack because there's no way to set compilerHost in the call to createProgram.

Is your feature request related to a problem? Please describe.

I can't seem to use Yarn PnP together with TypeScript without disabling TypeScript validation.

Describe the solution you'd like

Please allow overriding compilerHost; of course, even nicer would be if it all just worked out of the box.

Describe alternatives you've considered

The hack I've linked above is a workaround, so is setting ignoreBuildErrors: true.
