According to the documentation, the final character of an SGR mouse report is meant to be `M` for a button press and `m` for a button release. However it isn't clear what the final character should be for motion events, and we were using an `m` if there weren't any buttons held down at the time, while all other terminals used an `M`, regardless of the button state. This PR updates our implementation to match what everyone else is doing, since our interpretation of the spec was causing problems for some apps. ## Validation Steps Performed I've manually tested the new behavior in Vttest, and confirmed that our mouse reports now match Xterm more closely, and I've tested with v0.42.0 of Zellij, which was previous glitching badly in Windows Terminal, but now works correctly. I've also updated our unit tests for the SGR mouse mode to reflect the correct report format. Closes #18712 (cherry picked from commit 865f5e5) Service-Card-Id: PVTI_lADOAF3p4s4AxadtzgZ9_Ew Service-Version: 1.23

Validation Steps Performed
I've manually tested the new behavior in Vttest, and confirmed that our
mouse reports now match Xterm more closely, and I've tested with v0.42.0
of Zellij, which was previous glitching badly in Windows Terminal, but
now works correctly.
I've also updated our unit tests for the SGR mouse mode to reflect the
correct report format.
