chromium: update to 80.0.3987.87.

Hopefully should be resolving the frequent freezes experienced with 79.0.3945.130

Has this been tested to compile on all the relevant architectures?

Simply bumping the version number is not sufficient. A number of patches need to be removed, and a number of patches need to be added. I have it building for x86_64, but not for i686 or x86_64-musl yet.

Additionally, upstream has dropped jumbo_build, so all that has to be removed as well.

Here is a link to my current work:

I hope to fix i686 and x86_64-musl this weekend.

@pbui Thanks didn't realize there is so much patching between versions.

@mar1n3r0 To be fair, only major releases require extensive patching. Minor releases generally do not require much if any patching. Usually each major release lasts about a month before the next one comes out and in between there are a few minor security releases.

@mar1n3r0 Can you checkout #18955 ?
