* Refactor JSDoc types to Typescript types

When the caret is on a Typescript declaration that has no type, but does
have a JSDoc annotation with a type, this refactor will add the
Typescript equivalent of the JSDoc type.

Notes:

1. This doesn't delete the JSDoc comment or delete parts of it. In fact,
due to bugs in trivia handling, it sometimes duplicates the comment.
These bugs are tracked in #18626.

2. As a bonus, when `noImplicitAny: true`, this shows up as a code fix in VS Code
whenever there is a no-implicit-any error. With `noImplicityAny: false`,
this code must be invoked via the refactoring command.

* Test:refactor JSDoc types to Typescript types

* Change refactoring name and description

* Move filenames to match refactoring rename

* Transform jsdoc types in the refactor, not emitter

The emitter now understands JSDoc types but emits them in the original
format.

* Correctly transform jsdoc parameter types

And give a better name for rest params

* Convert all JSDoc parameters and return types of functions

* Add and update jsdoc annotation refactoring tests

* Convert @template tag to type parameters in refactor

* Test refactor of JSDoc @template tag

* Fix duplicated JSDoc comments

Incorporate suppressLeadingAndTrailingTrivia just added by @amcasey.
