gitlab: convert old REVIEWERS into GitLab's CODEOWNERS

The old REVIEWERS file was useful back in the mailing lists days, but
nowadays we use GitLab, and we tag people by using their usernames, not
email addresses.

Most of us know each other's usernames by now, but documentation like
this is not meant for us but for everyone else, so that they can talk to
us.

Let's convert the file into GitLab's CODEOWNERS format, which maps files
in the repository to GitLab users that people can look up or tag in
their issues or merge requests.

+# As of GitLab 14.3, all features surrounding this file are premium-only,

-Overview:
-
-	This file is similar in syntax (or more precisly a subset) of what is
-	used by the MAINTAINERS file in the linux kernel.
-	The purpose is not exactly the same the MAINTAINERS file in the linux
-	kernel, as there are not official/formal maintainers of different
-	subsystems in mesa, but is meant to give an idea of who to CC for
-	various patches for review.
-
-Descriptions of section entries:
-
-	R: Designated reviewer: FullName <address@domain>
-	   These reviewers should be CCed on patches.
-	F: Files and directories with wildcard patterns.
-	   A trailing slash includes all files and subdirectory files.
-	   F:	drivers/net/	all files in and below drivers/net
-	   F:	drivers/net/*	all files in drivers/net, but not below
-	   F:	*/net/*		all files in "any top level directory"/net
-	   One pattern per line.  Multiple F: lines acceptable.
-
-Maintainers List (try to look for most precise areas first)
-
-Note: this is an opt-in system, I have not tried to add anyone who hasn't
-either asked me or sent a patch to add themselves.
