[Keymap] Rework my Tsangan layout; turn off mousekeys (#8836)

* Give Tsangan layout a real Fn2 layer

* Disable mouse keys to work around qmk#8323

I don't actually use this feature, so there's no reason for it to be
enabled anyway, and it seems to cause spurious wakeups on Windows.

 # bcat's 60% Tsangan HHKB layout
 
-This is a normal Tsangan/HHKB (split backspace, split right shift) layout with
-arrow and navigation keys that match a standard HHKB layout. Additionally, the
-redundant right Super key on the bottom row actives an adjust layer with
-controls for RGB underglow and backlight, as well as media keys centered around
-the ESDF cluster.
+This is a Tsangan/HHKB (split backspace, split right shift) layout following
+the [traditional HHKB layout](https://deskthority.net/wiki/HHKB_Professional2)
+with a few changes:
+
+* The Delete key is mapped as Backspace (HHKB DIP switch 3).
+
+* The Alt and Super keys are swapped to put Alt directly adjacent to the
+spacebar (HHKB DIP switch 5).
+
+* The left Super key is replaced with another Function key (HHKB DIP switch 2).
+Unlike on the real HHKB, this key triggers a different Function 2 layer. (This
+also helps prevent accidental Super key presses while gaming.)
+
+* The Function 2 layer contains reset keys, RGB underglow and backlight
+controls (in place of the arrow and navigation keys), and media controls
+(centered around the ESDF cluster).
+
+* The Function 2 layer also has the F1-F12 keys mapped just like the Function 1
+layer. This is a concession to gaming because it enables these keys to be
+easily typed with the left hand, without taking the right hand off the mouse.
+
+* The leftmost and rightmost bottom row keys are mapped to Ctrl rather than
+anything more useful because most of my Tsangan PCBs actually have HHKB plates
+and/or blockers, so there aren't switches installed in those positions.
