[PATCH] tcg/perf: Placate clang-21's -Wdefault-const-init-field-unsafe

[Ilya Leoshkevich <iii@linux.ibm.com>]

clang-21 complains about the const "name" field in struct debug_entry.
While this warning may be too aggressive, there is not too much value
in having const there, so just drop it.

Note: in addition to this fix, I had to turn off the following clang-21
warnings to make the build work:

* -Wno-parentheses-equality
* -Wno-unused-value
* -Wno-tautological-unsigned-enum-zero-compare
* -Wno-tautological-compare
