[vim/vim] Add exists_info() for the definition of a builtin function or v: variable (PR #21293)
h_east
Problem: There is no way to get the definition of a builtin function
(the number of arguments, their types, the return type) or of a v:
variable (its type, whether it is read-only) from Vim script. A
language server has to parse the help text for it.
Solution: Add exists_info({expr}) which takes the notation of exists()
and returns a Dict with the definition: "*funcname" or "?funcname"
for a builtin function, "v:name" for a predefined Vim variable.
The other notations are not supported yet and return an empty Dict.

chrisbra left a comment (vim/vim#21293)Is this good now? Shall I merge each commit separately or you think a single squashed commit is okay?

Yeah. I've squashed the commits. I also updated the PR title and description.
