Do not reject valid SBC codec parameters

Fixes logic in A2DP_CodecInfoMatchesCapabilitySbc that could otherwise
reject valid SBC codec parameters, leading to A2DP being disconnected.

Example:
Tesla Model S - min bitpool = 2; max bitpool = 60
Android - min bitpool = 2; max bitpool = 53

Bug: 32688022
Test: Added test to test_a2dp_is_source_codec_supported to cover this bug
