fix: disable indirect detection if any stack calls
Don't know if kernels will be initialized in the order needed to check for indirect accesses in stack calls. Remove now unused functionPointerWithIndirectAccessExists and reading this value from zebin. Related-To: NEO-12235 Signed-off-by: Dominik Dabek <[email protected]> Source: ad22937
