Add support for Vial

Tap dances aren't supported in Vial, so we need to remove them.
To do this, we define U_TD_* keycodes, which default to tap dances if
Vial is not enabled and revert to standard keycodes if Vial is enabled.
To change the keycodes in the miryoku_layer_alternatives.h, the
following command was executed:
sed -i -e 's/TD(U_TD_BOOT)/U_TD_KC_BOOT /' -e 's/TD(U_TD_U_TAP)/U_TD_TAP      /' \
       -e 's/TD(U_TD_U_EXTRA)/U_TD_EXTRA      /' -e 's/TD(U_TD_U_BASE)/U_TD_BASE      /' \
       -e 's/TD(U_TD_U_FUN)/U_TD_FUN      /' -e 's/TD(U_TD_U_MEDIA)/U_TD_MEDIA      /' \
       -e 's/TD(U_TD_U_NAV)/U_TD_NAV      /' -e 's/TD(U_TD_U_NUM)/U_TD_NUM      /' \
       -e 's/TD(U_TD_U_MOUSE)/U_TD_MOUSE      /' -e 's/TD(U_TD_U_SYM)/U_TD_SYM      /' \
