edk2: Add .git-blame-ignore-revs file

Add a .git-blame-ignore-revs file containing the hashes of every
uncrustify format commit as retrieved in:
	git log --oneline --no-abbrev-commit  | grep "uncrustify"

This file can be used by tools (such as GitHub[1]) to ignore
certain revisions when git blame-ing a file.

It can also be trivially usable locally by doing something akin
to:
	git config blame.ignoreRevsFile .git-blame-ignore-revs

It may also be desirable in the future to add more commits to it.
