[LLDB][Test] Fix the test case of listing verbose break info on Windows (#85200)

I noticed a failure of [running LLDB test suites on Windows
AArch64](https://lab.llvm.org/buildbot/#/builders/219/builds/9849). The
failed test case is about
checking output of command `breakpoint list -v -L c++`, and an mismatch
on the demangled
name of a function occurred. The test case expects `ns::func(void)`, but
on Windows it is `int ns::func(void)`.
It results from the different mangling scheme used by MSVC, and the
comparison is as follows:

| Scheme | Mangled | Demangled (fully) | Note |
| --- | --- | --- | --- |
| MSVC | `?func@ns@@YAHXZ` | `int __cdecl ns::func(void)` |
[Godbolt](https://godbolt.org/z/5ns8c7xW3) (I have no available Windows
device) |
| Itanium | `_ZN2ns4funcEv` | `ns::func()` | |

According to the current use of MSVC demangling,


https://github.com/llvm/llvm-project/blob/8f68022f8e6e54d1aeae4ed301f5a015963089b7/lldb/source/Core/Mangled.cpp#L128-L143

the `__cdecl` specifier is not part of the name. However, the function's
parameter types should be present
as ` llvm::MSDF_NoVariableType` [does not affect a symbol for
functions](https://github.com/llvm/llvm-project/blob/8f68022f8e6e54d1aeae4ed301f5a015963089b7/llvm/lib/Demangle/MicrosoftDemangleNodes.cpp#L417-L453).

Therefore, it is inappropriate to assume the demangled name are the same
on all platforms. Instead of tweaking the
existing code of demangling to get the same (demangled) name, I think it
is more reasonable to modify the test case.

[lldb] Print mangled names with verbose break list (#84071)

When debugging LLDB itself, it can often be useful to know the mangled
name of the function where a breakpoint is set. Since the `--verbose`
setting of `break --list` is aimed at debugging LLDB, this patch makes
it so that the mangled name is also printed in that mode.

Note about testing: since mangling is not the same on Windows and Linux,
the test refrains from hardcoding mangled names.

According to the git log (d9442afba1bd6), this test has never been

it passes and it is useful, so this commit enables it.
