Profiler wrapper to allow for cudaDeviceSynchronize (#738)

* add warpx profiler wrapper

* call WX profiler wrapper instead of BL

* EOL and cleaning

* add doc on profile syncs

* do not use PROFILE macros in .H files

* replace WX_PROFILE with WARPX_PROFILE and use bool instead of int

* typo

* this file shouldn't be there
