- Fixes#22763
The XMB's video player boots the ME in mode 3 through sceMeCore_driver's
sceMeBootStart (5dff5c50), where games get mode 2. Mode 3 only changes the
argument to ME command 0x185 (me_wrapper.prx), and the player sets the AAC
context flag at 0x2d on anything newer than a PSP-1000 and plays those
files, so sceAudiocodecInit now accepts the 0x2c/0x2d flags in mode 3.
Games still get the failure pspautotests audio/audiocodec/context records.
Also implements the two vaudio calls the player uses: a ChReserveBuffering
that routes each buffer through an ME effect (E8E78DC8), and the setter for
its parameter (504E4745). The effect isn't known, so audio goes out as is.
