if TAPPING_TOGGLE is 1, then tap a single time should toggle the mods on/off each tap.

Previously this was broken, this fixes it. This allows the same key to either hold (momentary mod) or tap (toggle mod, like capslock).

This reverts commit c17b8a599e.

The commit made compile error and its intention is unclear.

Adding the makefile options ADB_MOUSE_ENABLE and ADB_MOUSE_ACCMAX.
Might have gone overboard with comments, and tried but failed at not
adding more than necessary outside the converter/adb_usb/ folder.

Keypresses would be forgotten if they began while ghosting, even if they
were still pressed after ghosting ended.
