[1800/2211] LINK(DLL) accessibility.dll accessibility.dll.lib accessibility.dll.pdb

GPU Win debug builders have the following gn args:

ffmpeg_branding = "Chrome"
proprietary_codecs = true

If I just comment them out, then compile succeeds

There are two issues

1) https://chromium-review.googlesource.com/c/chromium/src/+/1144456 caused this link failure, so it needs to be reverted

2) why other win debug builders don't have the above two gn args?

In order to revert the culprit CL, https://chromium-review.googlesource.com/c/chromium/src/+/1149153 also needs to be reverted.

Both related CLs are reverted. Locally I confirmed that should fix the link failure.

OK I'll take a look at how to reland fixed version of #3.1, then #4.  I'll track in the original bugs (860420 and 584384).

 Issue 867495  has been merged into this issue.

Fix of the link failure is included in the reland CL, currently in CQ: https://chromium-review.googlesource.com/c/chromium/src/+/1150247
