uwb(interface): Add a package for Android specific params in UCI

Along with the FIRA standard defined UCI specification, Android needs to
support some Android specific commands/params (uses vendor carve-outs in
the specifications). Use this new package to explicitly specify these
Android specific commands/params.

Note: This package is not tied to main UWB HAL interface and should be
updatable between dessert releases (infra changes needed to support
this still needs to be figured out).
