wrapper objects: for OwnedArtifacts, which are the most numerous during builds, and for Labels for TransitiveTraversalValues, which are the most numerous during queries.

The only input to FdoSupport.prepareToBuild is now the exec root, and
changes to that invalidate the entire server anyway.

options actually needed by the fragment. This protects against, e.g.,
unnecessarily duplicating CppConfiguration instances when only Java flags
change.
This is a recommit of ca1b21ac6d8a58041db822725b42de151b163dee which was
rolled back because it broke LIPO.
This change is particularly important for dynamic configurations, which may
mix and match fragments arbitrarily throughout a build. This not only has
performance implications, but also correctness implications: code that
expects two configured targets to have the same fragment (value) shouldn't
break just because the second CT's configuration is a trimmed version of the
first's.
The original change breaks FDO/LIPO because CppConfiguration can't be
shared across configurations. That's because it mutates state when
prepareHook() is called, and each configuration calls prepareHook. We
should ultimately solve this by refactoring the FDO/LIPO implementation
but don't want to block dynamic configuration progress on that. So this
change only enables trimming for dynamic configurations.

*** Reason for rollback ***
Broke some alipo builds. I had to leave in the change to TransitiveTargetFunctionTest, which is relied upon by follow-up CLs.
*** Original change description ***
Pre-trim build options for all remaining calls to ConfigurationFragment.key. Move
the trimming logic into key() itself to:
a) eliminate code redundancy
b) guarantee all future calls to key() also do this.

The headers were modified with
`find . -type f -exec 'sed' '-Ei' 's|Copyright 201([45]) Google|Copyright 201\1 The Bazel Authors|' '{}' ';'`
And manual edit for not Google owned copyright. Because of the nature of ijar, I did not modified the header of file owned by Alan Donovan.
The list of authors were extracted from the git log. It is missing older Google contributors that can be added on-demand.
