Remove operationTuple.

Removed operationTuple from Model in the HAL, as the data type was
redundant information.

Removed	supportedOperationTuples from Capabilities, as real drivers need
more complex restrictions than this provided.  For the OC-MR1, we'll just
rely on getSupportedNodes.

Also removed the unused	cachesCompilation.

Bug: 63905942
Test: Compiled and ran tests.
