Antonio Maiorano b6e1bc7d5d tint: Fix C++ UB when shifting abstract 0 left by >= 64 
In WGSL, we can shift left abstracts by >= 64, as long as the result is
representable in the data type we choose for it. When shifting 0, we can
shift by any positive u32 value (result is always 0), but in C++, it's
UB to shift by more than the bit width of the data type, so we need to
handle this. This bug was caught by ClusterFuzz.
