[Docs] Random Fixes (#8340)

* fix CLI section links in the Summary

* fix heading in Pointing Device doc

* fix headings in PS/2 Mouse Support doc

* add explicit section ids to I2C Master Driver doc

* reformat GPIO Controls table

Much like the I2C Master Driver doc, I found this a bit less than ideal to read. (The table was actually wider than the space available for it.)

Reformatted so each GPIO function is an H3 heading, followed by a paragraph and a table of each architecture's old-style function.

* migrate changes from I2C Master Driver doc to Japanese translation

* add explicit anchors to I2C Master Driver docs

* fix code block language markers

The language markers are case-sensitive; using the wrong case means the syntax highlighting doesn't work.

Good: ```c
Bad: ```C

* restore Japanese I2C Master Driver doc to current master

Can't update the internal tracking references accurately until the changes to the English doc are committed to master.

* add explicit anchors to edited files

* change ChibiOS/ARM to ARM/ChibiOS

Because ARM/ATSAM is also a thing that exists.

* fix code block language markers again

Used the wrong markers in a few spots. Also these are apparently always supposed to be lowercase.

* add section anchors to cli.md

* restore table formatting on GPIO Control doc

* remove changes to _summary.md
