This change fixes the following gcc build errors:
```
../../runtime/vm/simulator_arm.cc:1403:44: error: ‘function’ attribute directive ignored [-Werror=attributes]
1403 | int32_t r4) {
| ^
../../runtime/vm/simulator_arm.cc:1417:47: error: ‘function’ attribute directive ignored [-Werror=attributes]
1417 | double d1) {
| ^
cc1plus: note: unrecognized command-line option ‘-Wno-unused-private-field’ may have been intended to silence earlier diagnostics
cc1plus: all warnings being treated as errors
```
It looks like gcc doesn't support [[no_sanitize("function")]]
attribute, so limit its usage to clang.
TEST=ci
