releasetools: Track edify function API changes.

In particular, it replaces the generated calls to edify function of
`apply_patch()` and `apply_patch_check()` with `patch_partition()` and
`patch_partition_check()` instead.

It adds two functions to EdifyGenerator: PatchPartition() and
PatchPartitionCheck() for Python releasetools callers. It also tries to
handle the callers of obsolete EdifyGenerator.PatchCheck() and
EdifyGenerator.ApplyPatch(), if their inputs are in known format.
Otherwise it raises an exception to avoid generating an OTA that updater
doesn't understand.

It requires the matching updater changes in the same topic.

Bug: 110106408
Test: Generate an incremental package with the new script and updater.
      Apply the package on device.
Test: Revert the change in ota_from_target_files.py, so that it calls
      the obsolete EdifyGenerator functions. Check that it generates the
      same incremental package.
