Fix stack limit on ASAN/MSAN (#14771)

Increase the reserved stack size in ASAN builds, as instrumentation use more stack.
Increase the max allowed stack size in some tests, and enable these tests under ASAN.
Use __builtin_frame_address(0), instead of some stack variable, when we need a stack address, as ASAN may store local variables outside of the real stack.

Clarify the stack limit exception message

Make it clearer why the size is not exactly zend.max_allowed_stack_size

Fix test failures when PHP is compiled without ZEND_CHECK_STACK_LIMIT

Skip tests under MSAN

Stack overflows can be detected as long as C stack frames between two
execute_ex() calls use less than zend.reserved_stack_size bytes of stack.

The default value of zend.reserved_stack_size accounts for the largest stack
users, but MSAN instrumentation increases usage considerably: php_pcre2_match
uses more than 200KiB of stack in some MSAN build, compared to 20KiB without MSAN
according to -fstack-usage.
