Provide a highp variable to MAKE_HIGH_BALLOT_RESULT

The MAKE_HIGH_BALLOT_RESULT macro assumes the input is 32bit.
Given a mediump variable, ex: gl_SubgroupSize, would produce an
undefined result when the input value is >= 16 and the computation
is in 16 bits.
Provide a highp input would ensure the computation is in 32 bits.

Affects:
  dEQP-VK.subgroups.ballot_other.*
