Maintainers.txt: update for filesystem area descriptions

Add comment describing new F: and X: tags for associating maintainership
sections with specific filesystem paths, including wildcards.

Add global section associating *all* code with devel@edk2.groups.io,
with a default '*' F: tag directing all modifications that do not hit a
rule to the stewards.

Also tag all files in top directory as maintained by the stewards.
