layers: Add MEMTRACK_INVALID_MEM_REGION error

Add new enum value "MEMTRACK_INVALID_MEM_REGION" to track case when a
region of an allocation bound to an image or buffer is not valid due
to the memory not being correctly updated.

This was previously aliased to USAGE_FLAG case which was masking the fact
that there are no tests written for this invalid mem region case.
