Fix invalid C cast when or-block returns a fixed array constant/variable with GCC 15.2.

Fixes #26442

Changes

  • Only use compound literal cast for brace-enclosed initializers (ArrayInit, StructInit), not for constants/variables
  • Add test case for or-block with fixed array constant

Test plan

  • v -cc gcc vlib/v/tests/options/option_fixed_arr_const_test.v passes
  • Verified test fails on master, passes with fix
