[LLDB] Show sub type of signals when debugging a core file
Previously we only looked at the si_signo field, so you got:
```
(lldb) bt
* thread #1, name = 'a.out.mte', stop reason = signal SIGSEGV
* frame #0: 0x00000000004007f4
```
This patch adds si_code so we can show:
```
(lldb) bt
* thread #1, name = 'a.out.mte', stop reason = signal SIGSEGV: sync tag check fault
* frame #0: 0x00000000004007f4
```
The order of errno and code was incorrect in ElfLinuxSigInfo::Parse.
It was the order that a "swapped" siginfo arch would use, which for Linux,
is only MIPS. We removed MIPS Linux support some time ago.
See:
https://github.com/torvalds/linux/blob/fe15c26ee26efa11741a7b632e9f23b01aca4cc6/include/uapi/asm-generic/siginfo.h#L121
A test is added using memory tagging faults. Which were the original
motivation for the changes.
