Software features and optimization

• [MT25x3] Added support for Bluetooth LE multi-link concurrent operation (1 slave and 4 master Bluetooth LE links).

Bug fixes

• [inear_noodles_headset_ref_design] Cannot power on the device after it’s powered off by unplugging the USB charger.
• [inear_noodles_headset_ref_design] Local music sometimes stops playing after switching to the next song.
• [inear_noodles_headset_ref_design] Local music volume is too high.
• [cord_free_headset_ref_design] Local music stops playing on a slave headset after disconnecting from Bluetooth on a smartphone.
• [bioband_ref_design] HRV cannot function properly, after executing the blood pressure unit.
• [MT7682, MT7686] Wi-Fi throughput is less than expected in A-MPDU. There are two frame aggregation mechanisms for 802.11n (A-MSDU and A-MPDU) that are used to reduce the package header size and improve the overall throughput. The type of frame aggregation is determined between Wi-Fi AP and Wi-Fi station. A memory leak issue is fixed when in A-MPDU resulting low throughput.
