[esp32_ble] Inline ble_addr_to_uint64 to eliminate call overhead

Browse Source 
Move ble_addr_to_uint64 from ble.cpp to ble.h as inline. This
eliminates the indirect call and Xtensa register window rotation
at all 3 call sites, most importantly in the BLE proxy hot path
(BluetoothProxy::parse_devices) which calls it per advertisement.

Saves 24 bytes of flash overall.
