Move expectations for manual tests to NeverFixTests

New expectations for manual WPT will be appended to NeverFixTests
following https://crrev.com/c/1269759. This CL moves the existing
expectations from TestExpectations to NeverFixTests.

Steps:
1. Move all "external/wpt.*-manual.*[ Skip ]" lines without platform
   specifiers from TestExpectations to NeverFixTests.
2. Replace Skip with WontFix and strip the bug links.
3. Move all manual WPT lines in NeverFixTests to the end of the file
   and sort.
