Move everything to ActionExecutionContext, and drop Executor whereever possible.
This clarifies the API, makes it simpler to test, and simplifies the code.

By specifying the flag "--debug_print_action_contexts", Bazel will print the contents of the internal SpawnActionContext and ContextMap maps, which allows developers to see which kind of actions are run using which strategy.
Example output of Bazel at HEAD:
$ ./output/bazel build --debug_print_action_contexts
INFO: SpawnActionContextMap: "" = LinuxSandboxedStrategy
INFO: SpawnActionContextMap: "Closure" = WorkerSpawnStrategy
INFO: SpawnActionContextMap: "Javac" = WorkerSpawnStrategy
INFO: ContextMap: Context = BazelWorkspaceStatusActionContext
INFO: ContextMap: CppCompileActionContext = SpawnGccStrategy
INFO: ContextMap: CppLinkActionContext = SpawnLinkStrategy
INFO: ContextMap: FileWriteActionContext = FileWriteStrategy
INFO: ContextMap: FilesetActionContext = FilesetActionContextImpl
INFO: ContextMap: IncludeScanningContext = DummyIncludeScanningContext
INFO: ContextMap: SpawnActionContext = LinuxSandboxedStrategy
INFO: ContextMap: SymlinkTreeActionContext = SymlinkTreeStrategy
INFO: ContextMap: TestActionContext = ExclusiveTestStrategy
(Can you spot the bug found by this feature here? The default TestActionContext is ExclusiveTestStrategy, which is probably not what we want.)

Drop the Spawn.getOwner() method, which was duplicating functionality
already available through Spawn.getResourceOwner(), in favor of the
latter. In order to do that, change Executor.reportSubcommand to take
a Spawn instance instead, which in turn requires updating all call
sites.
This is part of establishing Spawn as an abstraction for lower-level
local and remote execution in all cases instead of passing args, env,
input/output files and possibly other metadata as individual method
parameters to the underlying implementations.
In order for that to be maintainable, Spawn should be light-weight and
easy to construct correctly, and not contain too much unnecessary data.

This change is part of the mu-bazel effort, which aims to build a minimally
useful Bazel binary with most extraneous functionality removed. As part of
that, we want to enforce layering of packages. In particular, lib.actions must
not depend on lib.rules or lib.exec. lib.rules must not depend on lib.exec.
Moving these classes is a necessary step to enforce that layering.
