audio_route: use mixer_ctl_get/set_array
Rather than make individual calls to tinyalsa for every
value in each mixer control, which is expensive for linked
controls, use the array get/set functions instead. This
reduces the number of system calls that tinyalsa has to
make. The majority of controls are linked and have 1 or 2
values so the CPU overhead is small.

audio_route: skip missing controls
Mixer controls that are in mixer_paths.xml but missing from
the mixer should be skipped, otherwise arrays will be accessed
out of bounds. This happened in b/8893515.
Also print the missing control name to aid debugging.

audio_route: use ctl_index instead of searching
Store the ctl_index instead of the ctl in the path so
that path_apply() and path_reset() don't have to
do a linear search through all the controls each time
to locate the index.

Put audio_route into its own library
The audio_route library allows mixer paths to be
loaded from an XML file and can control a mixer
via tinyalsa. It contains useful functions that
can be factored out of the audio HAL.
