Bluedroid stack dynamic allocation changes to optimise DRAM usage

Browse Source 
Structures allocated dynamically:
tACL_CONN, tBTM_PM_MCB, tBTM_SEC_DEV_REC, tGATT_TCB, tGATT_CLCB, tL2C_LCB, tL2C_CCB, tSDP_RECORD
Total dynamic allocation size ~19KB.
Peak dram usage reduced by ~12KB when in BT classic + BLE scenario(1 a2dp sink + 1 BLE gatt server)
