vm_core.h (rb_thread_t): use 32-bit running_time_us
The current range based current values of:
TIME_QUANTUM_USEC=100000
RUBY_THREAD_PRIORITY_MAX=3
RUBY_THREAD_PRIORITY_MIN=-3
Gives a range of 12500..800000, plenty enough for a 32-bit
integer. Clamping this also reduces potential implementation
bugs between 32-bit and 64-bit platforms.
I may consider a further reduction to uint16_t in the future
for M:N threading, but some users may want slightly larger
time quantums.
