There is a regression issue introduced in
cfc268814a.
This PR was intended to update MIT licensed header from v9 to v10.
But it accidentally changed "portYIELD_FROM_ISR( x )" in MSVC-MingW/portmacro.h.
It caused "portYIELD_FROM_ISR( x )" does not return correct value to "prvProcessSimulatedInterrupts".
