Autotools: Normalize PHP_ADD_BUILD_DIR 1st argument (#15612)

The m4_normalize(m4_expand([$1])) expands the given argument if it
contains M4 macros, and then trims the items together into a space
separated string in an intuitive way.

Autotools: Expand m4_normalize sooner (#15018)

Quoted m4_normalize will expand and change its argument later in the
macro call when M4 is processing the *.m4 sources. Without quotes the
already normalized string is passed to the macro directly. In these
specific cases generated configure script is the same. This is more for
consistency to have this synced and not repeat the pattern too much
in the future when copy/pasting. Note, that many AC_* macros require
similar behavior already (for example, AC_CHECK_FUNCS.)

Fix check for newer versions of ICU (#14186)

* Fix check for newer versions of ICU

The previous test would always trigger, even if the version of ICU
installed didn't require C++17. This was because it incorrectly used
the `test` program, which broke the build on systems without a C++17
compiler.

Tested with macOS 14 and i 7.2.

* Fix broken ICU version check for definition

Same as the previous fix for C++17.

We also define these in php_stdint.h, but don't always include that

This is necessary for old compilers that use C99 rather than C11
semantics for stdint.h.

Enforce C++11 in ext/intl

ICU 59 already requires C++11 by default. The minimum version required
by the core is 50, which is compiled with at least C++11 in many distros
as package defs tell. Headers for ICU versions between ICU 50 and 58 look
fine when included for C++11 compilation, the linking is thereof not affected.

The macro PHP_CXX_COMPILE_STDCXX is based on
https://www.gnu.org/software/autoconf-archive/ax_cxx_compile_stdcxx.html
The patch consists on allowing to read the corresponding switch in a user
defined variable instead of enforcing CXXFLAGS globally. That way, every
ext or SAPI can decide, which C++ standard is to be used. The
documentation is provided in the m4 file.

C++11 is already somewhat older standard, C++14 were better. However
issues with GCC < 5.0 and some other compilers are possibly to hit back.
Still there's some time to check for C++14 for ext/intl, too. Having said
that, C++11 in ext/intl and a mechanism to determine features is a good step
towards better C++ support.
