Remove the ENABLE_PERFORMANCE_TIMELINE compile-time flag.

This purely-mechanical change kills off the PERFORMANCE_TIMELINE flag, which
should have no web-visible effect as Chromium never disabled the feature.

Remove the ENABLE_LEGACY_VIEWPORT_ADAPTION compile-time flag.

Chromium enabled this in https://bugs.webkit.org/show_bug.cgi?id=90991, ships
it on Android, and has no plans to turn the feature off. We should kill the
flag.
