Differentiate between cc library and binary

The cc library and cc binary (and other cc module types) are all
instances of cc.Module. So, to differentiate between them and make
sure that only appropriate library instances can be added to
native_shared/static_libs this adds a special sdkMemberTypes field to
Module which if set specifies the SdkMemberTypes the module supports.
If it is not set then the module type cannot be used in the sdk at all.

Corrects an issue with one of the tests where a prebuilt cc
library was added to the sdk instead of a source cc library.

Adds a new test to ensure that cc_library_(shared|static)_host module
types work with the sdk as well and another test to ensure that
cc_library can be used as either.
