Alessio Bazzica fcf1af3049 APM: add AudioProcessingImpl::capture_::applied_input_volume(_changed)
The `recommended_stream_analog_level()` getter is used to retrieve
both the applied and the recommended input volume. This behavior is
error-prone since the caller must know what is returned based on
the point in the code (namely, before/after the AGC has changed
the last applied input volume into a recommended level).

This CL is a first step to make clarity on which input volume is
handled in different parts of APM. Next in the pipeline: make
`recommended_stream_analog_level()` a trivial getter that always
returns the recommended level.

Main changes:
- When `recommended_stream_analog_level()` is called but
  `set_stream_analog_level()` is not called, APM logs an error
  and returns a fall-back volume (which should not be applied
  since, when `set_stream_analog_level()` is not called, no
  external input volume is expected to be present
- When APM is used without calling the `*_stream_analog_level()`
  methods (e.g., when the caller does not provide any input volume),
  the recorded AEC dumps won't store `Stream::applied_input_level`

Other changes:
- Removed `AudioProcessingImpl::capture_::prev_analog_mic_level`
- Removed redundant code in `GainController2` around detecting
  input volume changes (already done by APM)
- Adapted the `audioproc_f` and `unpack_aecdump` tools
- Data dumps clean-up: the applied and the recommended input
  volumes are now recorded in an AGC implementation agnostic way
