[MT] Tweak HPS algorithm parameters to improve CPU performance
This tweaks the HPS algorithm to improve performance at the expense of power
consumption. This is necessary to avoid audio underruns caused by the CPU
running out of juice and taking too long to turn on another core.
Bug: b/73172349
Test: Ran the the 10h duration test with the new logic, no underruns observed.
