Add _java_resource_types, _java_library_types, and _java_leaf_types.
These types, together with "group", define all existing invoker.type
values for all java targets. Since leaf types like android_apk are not
used as dependencies for other java targets, all java targets in deps
trees can be defined as either resources, libraries, or groups.

Naming conventions have also been improved. Now java targets must match
_java_resource_patterns if the target is a resource target. Otherwise,
it must match _java_library_patterns if the target is a library target.
Group targets can match either of those, but should prefer matching
_java_library_patterns since they are treated as library targets in the
java_group template.

Thus, target filtering is now simplified. To filter for resource targets
, simply use _java_resource_patterns. To filter for library targets, use
_java_library_patterns and ignore the ones that also match
_java_resource_patterns. To filter for any java target, use
_java_target_patterns, which is a simple concatenation of the other two
lists of patterns.

The assert in write_build_config has been updated to enforce naming
schemes accordingly. This enables assumptions about library and resource
targets such as __header, __impl, and the newly added __assetres, which
is defined on library targets to be its transitive list of all resource
target deps.

Now compile_resources targets can filter their deps so that they only
depend on transitive resource deps. This allows compile_resources to
not depend on java library targets, and unblocks header generation for
apk targets. Previously an apk's __header target would depend on
compile_resources to finish, while the compile_resources target would
depend on the rest of the java library dependencies (not headers),
completely removing any benefit of header compilation for apk targets.
