openal-soft: update to 1.23.1.

openal-soft-1.23.1:

    Implemented the AL_SOFT_UHJ_ex extension.

    Implemented the AL_SOFT_buffer_length_query extension.

    Implemented the AL_SOFT_source_start_delay extension.

    Implemented the AL_EXT_STATIC_BUFFER extension.

    Fixed compiling with certain older versions of GCC.

    Fixed compiling as a submodule.

    Fixed compiling with newer versions of Oboe.

    Improved EAX effect version switching.

    Improved the quality of the reverb modulator.

    Improved performance of the cubic resampler.

    Added a compatibility option to restore AL_SOFT_buffer_sub_data. The option
    disables AL_EXT_SOURCE_RADIUS due to incompatibility.

    Reduced CPU usage when EAX is initialized and FXSlot0 or FXSlot1 are not
    used.

    Reduced memory usage for ADPCM buffer formats. They're no longer converted
    to 16-bit samples on load.
