AssetManager2: Allow out of order type/type spec

AssetManager2 assumes that RES_TABLE_TYPE_SPEC_TYPEs must immediately
precede their associated RES_TABLE_TYPE_TYPEs. This is not correct.
RES_TABLE_TYPE_SPEC_TYPEs must precede their associated
RES_TABLE_TYPE_TYPEs, but they do not need to immediately precede them.

For example, this is what we currently expect:

  RES_TABLE_TYPE_SPEC_TYPE id=1
  RES_TABLE_TYPE_TYPE id=1
  RES_TABLE_TYPE_SPEC_TYPE id=2
  RES_TABLE_TYPE_TYPE id=2

but this is also valid:

  RES_TABLE_TYPE_SPEC_TYPE id=1
  RES_TABLE_TYPE_SPEC_TYPE id=2
  RES_TABLE_TYPE_TYPE id=1
  RES_TABLE_TYPE_TYPE id=2
