add toString definitions for base types that have them

[bradzacher]

• RegExp: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp/toString
• Boolean: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Boolean/toString
• Error: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error/toString

This came up as a result of the @typescript-eslint/no-base-to-string rule which aims to prevent you from accidentally using the toString method from the Object type so that your output doesn't leak any [object Object].
typescript-eslint/typescript-eslint#1655

The rule relies upon every type that actually has a toString method declaring a toString method.

A few of our users ran into these cases that were reporting errors for them, even though they shouldn't.
I eyeballed the docs and the types and I am pretty certain that this completes the set of types that declare a toString.

@bradzacher can you open a bug for this? I think this needs some discussion on our side.

@typescript-bot perf test this because I'm not sure what adding methods to a primitive's apparent type will do.

Heya @sandersn, I've started to run the perf test suite on this PR at 6881e53. You can monitor the build here.

Update: The results are in!

@sandersn
The results of the perf run you requested are in!

Here they are:

The bug this PR is for is waiting for feedback from the community, so I'm going to close it in the meantime to keep the number of open PRs manageable. We can re-open if that bug is accepted.
