One shot support for swap hands (#8590) 
This commits add the SH_OS keycode, which works similarly to one shot
layers:
* while pressed, the keyboard is swapped
* if no keys were pressed while it was pressed, the next key press is
swapped

SH_OS also supports chaining with one shot layers:
OSL(x) + SH_OS + key interprets the key press on the oneshot layer.

The ONESHOT_TIMEOUT setting used by one shot keys and layers is also
used by oneshot swap hands. In the above chaining scenario the timeout
of the oneshot layer is reset when swap hands is activated.

Resolves #2682

Swap-Hands Action

The swap-hands action allows support for one-handed typing without requiring a separate layer. Set SWAP_HANDS_ENABLE in the Makefile and define a hand_swap_config entry in your keymap. Now whenever the ACTION_SWAP_HANDS command key is pressed the keyboard is mirrored. For instance, to type "Hello, World" on QWERTY you would type ^Ge^s^s^w^c W^wr^sd

Configuration

The configuration table is a simple 2-dimensional array to map from column/row to new column/row. Example hand_swap_config for Planck:

const keypos_t hand_swap_config[MATRIX_ROWS][MATRIX_COLS] = {
  {{11, 0}, {10, 0}, {9, 0}, {8, 0}, {7, 0}, {6, 0}, {5, 0}, {4, 0}, {3, 0}, {2, 0}, {1, 0}, {0, 0}},
  {{11, 1}, {10, 1}, {9, 1}, {8, 1}, {7, 1}, {6, 1}, {5, 1}, {4, 1}, {3, 1}, {2, 1}, {1, 1}, {0, 1}},
  {{11, 2}, {10, 2}, {9, 2}, {8, 2}, {7, 2}, {6, 2}, {5, 2}, {4, 2}, {3, 2}, {2, 2}, {1, 2}, {0, 2}},
  {{11, 3}, {10, 3}, {9, 3}, {8, 3}, {7, 3}, {6, 3}, {5, 3}, {4, 3}, {3, 3}, {2, 3}, {1, 3}, {0, 3}},
};

Note that the array indices are reversed same as the matrix and the values are of type keypos_t which is {col, row} and all values are zero-based. In the example above, hand_swap_config[2][4] (third row, fifth column) would return {7, 2} (third row, eighth column). Yes, this is confusing.

Swap Keycodes

Key Description
SH_T(key) Sends key with a tap; momentary swap when held.
SH_ON Turns on swapping and leaves it on.
SH_OFF Turn off swapping and leaves it off. Good for returning to a known state.
SH_MON Swaps hands when pressed, returns to normal when released (momentary).
SH_MOFF Momentarily turns off swap.
SH_TG Toggles swap on and off with every key press.
SH_TT Toggles with a tap; momentary when held.
SH_OS One shot swap hands: toggles while pressed or until next key press.
