[clang] Improve source location in binary type traits diagnostics (#88097)
This patch takes advantage of a recent NFC change that refactored
`EvaluateBinaryTypeTrait()` to accept `TypeSourceInfo` instead of
`QualType` c7db450e5c1a83ea768765dcdedfd50f3358d418.
Before:
```
test2.cpp:105:55: error: variable length arrays are not supported in '__is_layout_compatible'
105 | static_assert(!__is_layout_compatible(int[n], int[n]));
| ^
test2.cpp:125:76: error: incomplete type 'CStructIncomplete' where a complete type is required
125 | static_assert(__is_layout_compatible(CStructIncomplete, CStructIncomplete));
| ^
```
After:
```
test2.cpp:105:41: error: variable length arrays are not supported in '__is_layout_compatible'
105 | static_assert(!__is_layout_compatible(int[n], int[n]));
| ^
test2.cpp:125:40: error: incomplete type 'CStructIncomplete' where a complete type is required
125 | static_assert(__is_layout_compatible(CStructIncomplete, CStructIncomplete));
| ^
```
