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

Autotools: Replace AC_MSG_ERROR with AC_MSG_FAILURE (#15209)

This replaces the AC_MSG_ERROR with AC_MSG_FAILURE, where appropriate.

The AC_MSG_ERROR outputs given message and exits the configure step. The
AC_MSG_FAILURE does the same but also automatically outputs additional
message "See 'config.log' for more details." which might help directing
the user where to look further.

The AC_MSG_ERROR is used for errors where current test step isn't logged
in the config.log and wouldn't make sense, and AC_MSG_FAILURE is mostly
used in cases of library checks, compilation tests, headers checked with
AC_CHECK_HEADER* and similar tests that are also logged in the
config.log.

AC_MSG_ERROR([Sanity check failed.]) output:

```
configure: error: Sanity check failed.
```

AC_MSG_FAILURE([Sanity check failed.]) output:

```
configure: error: in '/path/to/php-src':
configure: error: Sanity check failed.
See 'config.log' for more details
```

Autotools: Append hash and opcache build directories (#15132)

When building in out-of-source directory, instead of creating these
build directories right away, this appends them to the list and creates
them at the end of configure phase. These don't need to be created
immediately as no files are generated in these extensions before the
configure phase is finished.

Also, the PHP_ADD_BUILD_DIR is moved after the PHP_NEW_EXTENSION when
the more common $ext_builddir variable is available (the ext/<extension>
isn't available when building with phpize).

Fix linking library for POSIX shared memory functions (#13822)

The POSIX shared memory object operations functions (shm_open,
shm_unlink...) are in:
* C library on most systems (newer Linux, Solaris 11.4, illumos, BSD*,
macOS, Haiku, etc.)
* real-time (rt) library on older Linux distributions and Solaris <= 10.

Haiku C library (called root library) on Haiku is linked in by default.

Previous check always added additional rt or root library to global LIBS
and rt to OPCACHE_SHARED_LIBADD. Now, the library containing shm_open is
linked as needed to the always shared opcache extension.

This also removes unused HAVE_SHM_OPEN and HAVE_LIBROOT symbols.
