fix (for one case of...) [#33949] T_ALT_TRANSFORM conflicts with "emulate 3 button mouse"

ShrinkFatten operator now uses scale key to toggle 'Even thickness' option.
With the default keymap this is Alt+S,S.

Added functionality so the header print can get the key used for the modal keymap, some other operators should make use of this too.
