1. Added new API functions that can add 32 and 128-bit UUID to the EIR data
when these UUIDs are set in SDP.
The old functions that only work with 16-bit UUIDs have been left
unchanged to avoid having to redo code that already utilizes them.
2. Fixed bug with zero handler return in btc_sdp.c
sdp_create_record.handle in tBTA_SDP struct wasn't saved before.
Because of it Bluetooth stack always returned zero handler to
application callback.
Closes https://github.com/espressif/esp-idf/issues/11529
use eventgroup to sync spp_vfs_write

revert functions like spp_find_slot_by_xxx
fix vfs read bug when peer close
Prevent a remote device from doing a Bluetooth Impersonation Attack
(BIAS) by:
- Preventing remote device to downgrade secure connection
feature mask. Secure connection feature mask should remain same or
increase to enabled in link key generation and authentication.
- Doing a mutual authentication during Legacy Authentication.
