Fix bug(s) in combining and chaining GrTextureOps

The repro case for this bug is where we have ~700 non-AA texture ops
with a few coverage-AA texture ops sprinkled throughout. In the old
system this could result in the quad limits being exceeded bc the
AA type for the entire run was believed to be non-AA during the creation
phase only to find that it was actually coverage-AA at execution time.
This problem manifested in both the bulk creation method and the
1-by-1/chaining creation method.

Note: in the original repro case every texture op has its own separate
texture so the problem manifests in the chaining case.
