fix(completion): complete drive-letter filepath on Windows #36353

Problem:
On MSWIN, file completion (CTRL-X CTRL-F) only works for the current
drive (so not for actual absolute paths), since drive letters are never
included in the completion pattern.

e.g. when completing "F:\Hello" Nvim currently completes "\Hello"
which is relative to the current drive/volume.

vim solves this by adding ':' to the default 'isfname' value on mswin,
but that causes issues as ':' is not a valid windows path char anywhere
_except_ after the drive letter.

Solution:
detect drive letters in front of the path when creating the completion
pattern.
