Bug: 78329453

Update to upstream at https://github.com/libjpeg-turbo/libjpeg-turbo/tree/2.0.0

This includes a fix for a bug that could result in an infinite loop.

ChangeLog.md contains detailed changes about the upstream library. Changes
I made are below:
- Remove files that are no longer in upstream, and include all current
  files from upstream.
- Update various references to the version.

Android.bp:
- Update to build new files/files in new locations.
- Run bpfmt

README.android:
- Remove cherry-pick references, as they are no longer needed.
- Remove modification in jsimdext.inc, which no longer appears to be
  necessary.

README.version:
- Use the github URL, as it is now the official upstream build
- Replace msarett as OWNER, as he no longer works on this project
- Update the version
