std.Target: add PSX
Adds target info for the PSX. Builds fine with the following:
```zig
const target = b.resolveTargetQuery(.{
.os_tag = .psx,
.cpu_arch = .mipsel,
});
```
the only "problem" being that it spits out an error from LLVM even
though generating an object file succeeds:
```sh
❯ zig build
install
└─ install generated to main.o
└─ compile obj obj Debug mipsel-psx failure
error: warning: MIPS-I support is experimental
```
