Add max decimal place option to recorder.

[0mdc]

Motivation and Context

This changes the gfx-replay Recorder to make the maximum float decimal places configurable.

This is an easy way to increase performance of JSON-based systems, as well as making the output text more compact.

Example usage:

sim.gfx_replay_manager.set_max_decimal_places(3)
[...]
sim.gfx_replay_manager.save_keyframe()
keyframe = sim.gfx_replay_manager.write_saved_keyframes_to_string()

Example data (update frames):

Default	3 Decimal Places
4223 bytes	3656 bytes

How Has This Been Tested

Added a unit test, and tested locally on the HITL tool.

Just FYI, there's TestSuite::Compare::StringContains and also TestSuite::Compare::StringNotContains for better failure diagnostics.
