Add a tracing API and instrument key functions in order to profile
aapt2 bottleneck. The API allows to generate systrace fragment files.
Impact on performance is neglibible with each Trace requiring less
than 1us and the final Flush operation at the end of a command
requiring around 40us.

Adds --exclude-configs to remove matching configs from resulting APK. This matches on explicitness, so if the resource contains all the flags set by the option exactly, it will be removed, but not the other way around.
"--exclude-configs fr" with fr-land resource will remove.
"--exclude-configs fr-land" with fr resource will not remove.
