sluicebox 388f3a02ef SCI32: Create kScummVMSleep for script patches
We have several SCI32 script patches that replace kGetTime spin loops
with calls to kWait for the intended delay. This prevents blocking
the main thread and allows ScummVM to be responsive and update the
screen. But kWait isn't a simple sleep, it's a throttling function,
and the duration that it sleeps (if any) is determined by the time
since it was last called. kWait was only in SCI16 interpreters so it
had to be restored to SCI32 and this required a further workaround
for Phant2 compatibility.

Now we have a dedicated custom kernel function, kScummVMSleep, which
does a simple sleep so that SCI32 script patch delays are consistent
and the Phant2 workaround isn't needed. This approach is similar to
kScummVMSaveLoad.
