perf: cache literal *ZVal at compile time in runZVal

Scalar literals (int/float/string/bool/null) are now wrapped
once and the same *ZVal is reused on every Run() — eliminates
the per-iter ZInt.ZVal alloc that dominated tight loops.

For for ($i = 0; $i < 100000; $i++) the literal 100000 went
from 100000 allocs/iter to 1.

Bench impact (vs. baseline):
  Arithmetic    -32% allocs, -15% CPU
  StringConcat  -34% allocs, -19% CPU
  ArrayOps      -15% allocs, -14% CPU
  FunctionCalls  -6% allocs,  -9% CPU
