Revert Oboe pin to main branch for latest ADPF and latency features

Oboe main has 79 commits since v1.10.0 including workload management
APIs, spatialization, PCM offload, and API 36 compatibility that are
valuable for a low-latency rhythm game. Releases are infrequent (~yearly)
so main is the better choice.
