package/qt5/qt5webkit: fix build with ICU >= 76

Browse Source 
Since the bump of ICU from ICU 73 to ICU 77 in commit
dcee99507c, the build of qt5webkit fails
with:

/home/thomas/buildroot/br/output-all/host/aarch64-buildroot-linux-gnu/sysroot/usr/include/unicode/char16ptr.h:271:38: error: ‘enable_if_t’ in namespace ‘std’ does not name a template type
  271 | template<typename T, typename = std::enable_if_t<std::is_same_v<T, UChar>>>
      |                                      ^~~~~~~~~~~

We taken two patches from Arch Linux, one which is a partial upstream
backport, and another which was submitted upstream, to address this
build issue.

Subject: [PATCH] Source/WTF/wtf/Platform.h: fix build with newer
versions of ICU
Partial backport of r260554 (79fe19caf)
In particular, we need -DU_SHOW_CPLUSPLUS_API=0 to avoid compilation
errors in C++ parts of ICU headers which we are not using anyway.

Subject: [PATCH] Disable ICU C++ header-only APIs, introduced in ICU 76
They require C++17 which we do not have, but we do not need them anyway.
