devel/llvm[789]: restore arm_bf16.h to ARM backend

arm_bf16.h is generated for both armv7 and aarch64 so move it back to
ARM.  We don't support AArch64 without ARM so we can just move it and
not need to worry about duplicate supression (I'd previously fixed the
issue in llvm19 in a more complicated manner so this change removes the
duplicate supression and documents why it's not needed.)

devel/llvm17: fix build with libc++ 19

As noted in the libc++ 19 release notes [1], std::char_traits<> is now
only provided for char, char8_t, char16_t, char32_t and wchar_t, and any
instantiation for other types will fail.

This causes devel/llvm17 to fail to compile with clang 19 and libc++
19, resulting in errors similar to:

    /usr/include/c++/v1/string:820:42: error: implicit instantiation of
undefined template 'std::char_traits<unsigned char>'

devel/llvm17: install all heaaders with clang

Historically we've been unable to build FreeBSD with the full set due to
conflicts and/or missing features between the compiler provided headers
and FreeBSD's headers. I've verified that I can build world and kernel
on the main, stable/14, and stable/13 branches for amd64 so let's give
it another try in broader testing.

Clang 18 is more strict in checking inline assembly constraints,

devel/llvm17: merge upstream llvm fixes

These fixes were merged to the base LLVM compiler:
  158f4f30adb4 [Clang] Do not change the type of captured vars when checking
lambda constraints
  3ed9e9e3ace6 [Clang] Add captures to the instantiation scope of lambda call
operators

devel/llvm1[234567]: enable qsort sanatizer wrapper

I'd disabled it in 10.0.0 when it was found to be broken.  It was then
fixed in LLVM 12, but the patch was never never removed and I propogated
it along for several year.

devel/llvm17: remove obsolete powerpc patch

The lines immediatly below the inserted code do the same thing with
more elegance.

Technically this changes the package contents, but there is no
functional change so don't make everyone build with a PORTREVSION bump.
We'll do that soon enough when 17.0.3 comes out.

Fix a duplicate listing of arm_sve.h.  It is sufficent to include it only
in the Arm case becaues AArch64 always implies Arm in the port.

devel/llvm17: fix non-aarch64 plist issue

arm_sme_draft_spec_subject_to_change.h is an aarch64-specific header.
Reading the Cmakefiles, it appears arm_bf16.h and arm_sve.h are also
aarch64 not arm specific so move them.
