removing the layer of indirection of getting SkyKey out of ActionLookupKey, which uses more memory for no reason.

If we are running with a single source root and not going to set up the execroot (since we know how to resolve all packages), we can avoid tracking loaded packages, since they're only used to set up the execroot.

Blaze had its own class to avoid GC from varargs array creation for the precondition happy path. Guava now (mostly) implements these, making it unnecessary to maintain our own.
This change was almost entirely automated by search-and-replace. A few BUILD files needed fixing up since I removed an export of preconditions from lib:util, which was all done by add_deps. There was one incorrect usage of Preconditions that was caught by error prone (which checks Guava's version of Preconditions) that I had to change manually.

--noexperimental_enable_critical_path_profiling flags are all specified, then Bazel will delete Actions from ActionLookupValues as they are executed in order to save memory.
Because an already-run action may output an artifact that is only requested later in the build, we need to maintain a way for the artifact to look up the action. But in most cases we don't need to keep the action itself, just its output metadata.
Some actions unfortunately are needed post-execution, and so we special-case them.
Also includes dependency change with description:
Move action out of key. This keeps action references from polluting the graph -- actions are just stored in one SkyValue, instead of being present in SkyKeys.
This does mean additional memory used: we have a separate ActionLookupData object per Action executed. That may reach ~24M for million-action builds.

ConfiguredTargetValues. Also clear transitive packages for both, even for top-level targets.
This is not expected to save significant memory, but is expected to reduce the number of references to Packages, allowing them to be dropped more easily when discarding analysis cache and running in batch mode.

Except in action execution logic (ActionExecutionFunction, SkyframeActionExecutor, etc.), switch Action interface references to either ActionAnalysisMetadata if possible or ActionExecutionMetadata.

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.

- Label parsing can be simplified
- lib.syntax is only contains the code for Skylark and is reasonably independent from the problem domain of building things
This change is mostly only changes to imports declarations. The rest is reversing the dependency between :cmdline and :syntax and moving a tiny amount of code between Printer and FilesetEntry and the addition of SkylarkPrintableValue that I couldn't be bothered to separate out into its own change.
