vkd3d-shader/spirv: Cache numeric types without through the general declaration cache.

Browse Source 
Numeric types are used very frequently, and doing a tree search
each time one is needed tends to waste a lot of time.

I ran the compilation of ~1000 DXBC-TPF shaders randomly taken from
my collection and measured the performance using callgrind and the
kcachegrind "cycle count" estimation.

BEFORE:
 * 1,764,035,136 cycles
 * 1,767,948,767 cycles
 * 1,773,927,734 cycles

AFTER:
 * 1,472,384,755 cycles
 * 1,469,506,188 cycles
 * 1,470,191,425 cycles

So callgrind would estimate a 16% improvement at least.
