anv/pipeline: use unsigned long long constant to check enable vertex inputs

When initializing the ANV pipeline, one of the tasks is checking which
vertex inputs are enabled. This is done by checking if the enabled bits
in inputs_read.

But the mask to use is computed doing `(1 << (VERT_ATTRIB_GENERIC0 +
desc->location))`. The problem here is that if location is 15 or
greater, the sum is 32 or greater. But C is handling 1 as a 32-bit
integer, which means the displaced bit is out of range and thus the full
value is 0.

Thus, use 1ull, which is an unsigned long long value.

This fixes:
dEQP-VK.pipeline.vertex_input.max_attributes.16_attributes.binding_one_to_one.interleaved

v2: use 1ull instead of BITFIELD64_BIT() (Matt Turner)
