post_proc: Squash upstream changes

post_proc: disable effect immediately when routed to invalid devices

Offload effect is still perceived when invalid output device is
connected. We should send disable command immediately once phone is
routed to unexpected device and forbid effect enablement during
temporary disabled state.

post_proc: Fix improper datatype of EQ preset band level value

unsigned int causes negative band level turn out to be extreme large
value, which results in EQ works abnormally due to unexpected parameter
sent.

post_proc: add support for virtualizer capability query

Add extra virtualizer interfaces to keep align with aosp design.
Extended capabilities include:
- Stub interface to allow querying speaker angles.
- Force set output device as specific virtualize mode.
- Query virtualize mode

Stub function remains to be refined in sync with upcoming aosp
changes.

post_proc: remove unnecessary command size check

Up bound check for command size of EFFECT_CMD_SET_PARAM is not
applicable for DSP effect bundle. Remove the check to avoid parameter
not taking effect.

post_proc: explicitly disable virtualizer module if strength is 0

0 stength in DSP virtualizer is not equivalent to disable state as down
mix is still happening for multichannel inputs.

For better user experience, explicitly disable virtualizer module when
strength is 0.

post_proc: fix reverb processing issue when preset is set to NONE

Reverb effects are getting applied even after setting reverb preset
to REVERB_PRESET_NONE.
Preset NONE is used by client and is supposed to be equivalent to
disabled state, even though this preset is not supported in DSP.
Fix this issue by avoiding enable command from post processing HAL
to DSP when preset NONE is in use.

post_proc: fix crash in offload effect bundle during stop output

Effect bundle stop() frees mixer contol before doing module stop(),
whereas module's stop() still needs this control to send disable
command down the layer.
Crash is observed if memory associated with effect control is reused
and gets altered by the time mixer control is completed.
Move mixer control's deletion after module's stop() to fix this issue.
