Update ANGLE in WebKit to the version of 2020-03-27 to roll in the fix for anglebug.com/4504 (currently cherry-picked in WebKit) and others.
Status update: fixed a problem in the ANGLE roll script regarding how the commit ID is generated. Tighter validation in updated ANGLE uncovered a few bugs in VideoTextureCopierCV.cpp, but there seems to be one bug in ANGLE around rendering feedback loop detection for which I'm trying to create a standalone test case and report upstream in the ANGLE project.

The attached patch is purely an ANGLE roll - all corollary changes were made in Bug 209943. changes.diff has been automatically updated, and no manual changes were made during this roll aside from updating the Xcode project.
Note that there are important steps to take when updating ANGLE. See http://trac.webkit.org/wiki/UpdatingANGLE

No real value in the file/function list for a change done by a script like this one. I suggest omitting it as I have done with many other patches like this.
