Meta: Force semi-colon after MAKE_AK_NONXXXABLE()

Before, we had about these occurrence counts:
COPY: 13 without, 33 with
MOVE: 12 without, 28 with

Clearly, 'with' was the preferred way. However, this introduced double-semicolons
all over the place, and caused some warnings to trigger.

This patch *forces* the usage of a semi-colon when calling the macro,
by removing the semi-colon within the macro. (And thus also gets rid
of the double-semicolon.)
