Move metrics and time library to libbt-common

* libbt-osi is being deprecated and libbt-common will replace it
* Move recently implemented metrics library to libbt-common
* Move time library from libbt-osi to libbt-common and renamed as time_util
  to avoid potention name collision with system time libraries
* Need to keep time library for now because we need to use
  CLOCK_BOOTTIME that include system suspension time for A2DP encoding
* Use libchrome logging methods in metrics library
* Put both metrics and time_util into bluetooth::common namespace
* Return uint64_t for time_get_os_boottime_ms and update various
  receiver types
* Remove tBTM_CB.max_collision_delay and use the constant
  BTM_SEC_MAX_COLLISION_DELAY instead
