Jeff Tinker 0b3f41ec8d Support multiple codecs per crypto instance
The initial drm hidl hal implementation assumed one
codec per crypto instance, but in fact there can be
multiple codecs per crypto instance. This change
extends the drm hal to allow multiple memory heaps
per crypto plugin. It fixes the issue of mapping
memory frequently during playback.

bug:35275191

Test: manual verification with Play Movies on angler
and in binderized mode on marlin
