Description of Changes
Make the communication between the EE (input recording) and the GS (displaying the frame count via ImGui) thread-safe. Additionally fixes a bug where the frame count was +1 what it should actually be. See #10793, which this is a follow-up to. (This fixes a small bug from that as well.)
Rationale behind Changes
Good to have the correct value displayed (previously we would run into an issue where we would say that we're on a frame that doesn't exist yet; for example, if we'd written 580 frames to an input recording and were actively recording, we'd be on frame 581). And make the code operate in a way that's not subject to a potential race condition.
Suggested Testing Steps
Test input recording to make sure 1) the correct value is displayed and 2) nothing is broken.
