Remove more android struct tags from runtime created arch structs
to reduce the size of their names, which hit the 64kB limit in
runtime.StructOf if they are too long.

The filesystem object was available through ModuleContext.Fs(), but
gives too much access to the filesystem without enforicing correct
dependencies. In order to support sandboxing the soong_build
process move the filesystem into the Config. The next change will
make it private.

Avoid having to pass ModuleFactoryAdaptor to every call to
RegisterModuleType in a test by wrapping RegisterModuleType.

Add a test for the arch mutator in preparation for splitting it
into two mutators.

Runtime-created struct types have limit on the name of the type,
which is the full text of the fields in the struct. Avoid creating
runtime struct types when filtering produces an identical struct.
Also add tests and godoc for filterArchStruct.
