Event recording enhancements

[MatthewOwens]

Implements the feature request described in #2948. Added the following functions:

RLAPI void BeginEventRecording(bool displayText);
RLAPI void StopEventRecording(const char *fileName);
RLAPI void PlayEventRecording(const char *fileName, bool displayText);

This change also modifies the behavior of when PlayAutomationEvents is called. It will now play out a recorded event file from when PlayAutomationEvents is called, rather than only playing the file if CORE.Time.frameCounter < eventCount.

@MatthewOwens Thanks for the improvement! I need some time to review this API carefully, to align it with raylib.

Cheers for the review, I agree that a compilation flag approach would probably be better. I wasn't sure if you'd be open to an additional flag, but I'll switch to that approach and update the function names to better align with raylib's style.

Any concerns around the functionality changes regarding playing events?

@MatthewOwens I know it's been a while since this PR but API has been finally redesigned on commit: 99dac54
