* Rename TypeDefinitionProvider to TypeImeplementationProvider
**bug**
In #18346, I originally called the new go to implementation provider api `ImplementationProvider` which we then decided to rename to `TypeDefinitionProvider`. At the time, I didn't realize that a type definition was actually its own, unrelated concept.
**Fix**
Rename `TypeDefinitionProvider` to `TypeImplementationProvider` to make it clear what the purpose and use of this api is.

Fixes#17825Fixes#17770Fixes#17584
**Bug**
When typing two or more `.` in a row, we end up unexpectedly accepting suggestions in TS files. This is caused by the custom keybinding that ts registers for `.`.
**Fix**
Only accept the suggestion on `.` if the previous character is a valid identifier character.
* Move title to nls
