I noticed this discrepancy (last row of the matrix treated differently than the
others) when optimizing the input latency of my keyboard controller, see also
https://michael.stapelberg.ch/posts/2021-05-08-keyboard-input-latency-qmk-kinesis/
Before this commit, when tuning the delays I noticed ghost key presses when
pressing the F2 key, which is on the last row of the keyboard matrix: the
dead_grave key, which is on the first row of the keyboard matrix, would be
incorrectly detected as pressed.
After this commit, all keyboard matrix rows are interpreted correctly.
I suspect that my setup is more susceptible to this nuance than others because I
use GPIO_INPUT_PIN_DELAY=0 and hence don’t have another delay that might mask
the problem.

* Allow recording of the last matrix activity time, to simplify implementation of display timeouts and the like.
* Add requested changes from code review.
* Simplify split matrix last changed.
* Add modifier state to the split transport
This adds modifier state to the i2c and serial transport for split
keyboards. The purpose of this is to allow e.g. displaying modifier
state on the slave side of a split keyboard on an oled. This adds one
byte to the data transferred between halves.
This also fixes a missing ifdef guard for BLACKLIGHT_ENABLE.
Break modifiers into real/weak/oneshot
Fix incorrect slave serial mod setting
Fix typo in serial weal mod setter
Fix build errors for the I2C code that I introduced
Code cleanup and formatting per project preferences
Correctly get oneshot mods
Fix missing braces
Remove unneeded ifdef guard
Make the added state transport optional
Add documentation for the new define to enable this feature
Fix stray grave mark
