Enables Deep Profiling support in the player.
Deep profiling allows to instrument all C# method calls.
Note:
A Player built with the EnableDeepProfilingSupport option enabled might be significantly slower, than one built with this option disabled.
When this option is enabled, additional checks are inserted at the beginning and end of every C# Method. These checks will continually test if the Player is currently profiled in Deep Profile mode or not, which adds some overhead to their execution time. If the Player is indeed profiled in Deep Profile mode, the time to execute the method is going to be recorded, which adds some additional overhead. The overhead will not be fully attributed to the method that has been instrumented like this, but will affect the recorded execution time of the calling method as well.
