rts/RtsSymbols: Add AArch64 outline atomic operations

Fixes #22012.

Generated via:

```python
ops = []
ORDERINGS = [ 'relax', 'acq', 'rel', 'acq_rel' ]
for order in ORDERINGS:
    for n in [1,2,4,8]:
        for op in ['swp', 'ldadd', 'ldclr', 'ldeor', 'ldset']:
            ops.append(f'__aarch64_{op}{n}_{order}')

    for m in [1,2,4,8,16]:
        ops.append(f'__aarch64_cas{n}_{order}')

print('\n'.join(f'    SymE_NeedsProto({op}),' for op in sorted(ops)))
```
