Adds the target_version and target_clones attributes to diagnostic messages
for target_version semantics.
This is because the target_version/target_clones attributes affect the identity
of the decls, so need to be represented in diagnostics for them.
After this change diagnostics look like:
```
test.c:5:7: error: redefinition of ‘[[target_version("sve")]] foo’
5 | float foo () {return 2;}
| ^~~
test.c:2:7: note: previous definition of ‘[[target_version("sve")]] foo’ with
type ‘float(void)’
2 | float foo () {return 1;}
```
This only affects targets which use target_version (aarch64 and riscv).
