cglobal: Fall back to runtime intrinsic (#54914)
Our codegen for `cglobal` was sharing the `static_eval` code for symbols
with ccall. However, we do have full runtime emulation for this
intrinsic, so mandating that the symbol can be statically evaluated is
not required and causes semantic differences between the interpreter and
codegen, which is undesirable. Just fall back to the runtime intrinsic
instead.
