configure & build: Rework legacy GCC detection to parse versions outside of Jam.

Jam comparison logic is string-based, and so was detecting GCC >= 10
as being < 2. This rectifies that by removing the GCC version parsing
from Jam logic entirely, and setting various BuildConfig variables
instead.

Remove all invocations of SetSubDirSupportedPlatformsBeOSCompatible.

Use libstdc++, libsupc++ and libgcc from gcc_syslibs.

* Instead of faking libstdc++.so from libstdc++.a, use libstdc++.so
from the gcc_syslibs build feature for everything except x86_gcc2.
* Use libgcc_s.so from the gcc_syslibs build feature for everything but
x86_gcc2 (which still carries libgcc as part of libroot.so).
* Drop filtering of libgcc objects for libroot, as that is no longer
necessary since we're only using libgcc-as-single-object for libroot
with x86_gcc2, where the filtered object file doesn't exist. Should
the objects that used to be filtered cause any problems as part of
libgcc_s.so, we can always filter them as part of the gcc build.
* Use libsupc++.so from the gcc_syslibs build feature for everything but
x86_gcc2.
* Adjust all Jamfiles accordingly.
* Deactivate building of faked libstdc++.so for non-x86-gcc2. For
x86_gcc2, we still build libstdc++.so from the sources in the Haiku
source tree as part of the Haiku build .
* Put gcc_syslibs package onto the image, when needed.

Bring the hybrid translators back into the image.

More work towards hybrid support

* All packaging architecture dependent variables do now have a
respective suffix and are set up for each configured packaging
architecture, save for the kernel and boot loader variables, which
are still only set up for the primary architecture.
For convenience TARGET_PACKAGING_ARCH, TARGET_ARCH, TARGET_LIBSUPC++,
and TARGET_LIBSTDC++ are set to the respective values for the primary
packaging architecture by default.
* Introduce a set of MultiArch* rules to help with building targets for
multiple packaging architectures. Generally the respective targets are
(additionally) gristed with the packaging architecture. For libraries
the additional grist is usually omitted for the primary architecture
(e.g. libroot.so and <x86>libroot.so for x86_gcc2/x86 hybrid), so that
Jamfiles for targets built only for the primary architecture don't
need to be changed.
* Add multi-arch build support for all targets needed for the stage 1
cross devel package as well as for libbe (untested).

Remove the old "CVS" package rules

... and all their invocations.

Update libpng package

Also make use of new build feature rules

Complete outsourcing of zlib

* Add optional packages Zlib and Zlib-devel.
* Simplify the build feature section for zlib and also extract the
source package.
* Replace all remaining references to the zlib instance in the tree and
remove it.

zlib: added an optional build package, integrated to the build

* optional package for zlib 1.2.7
* keep zlib in build for the bootloader tarfs

libpng and jpeg: build against optional packages.

* added optional feature package for libpng 1.5.12 gcc4/gcc2 x86 and ppc
* drop libpng sources and headers from the tree.
* added optional feature package for jpeg 8d gcc4/gcc2 x86 and ppc
* drop jpeg sources and headers from the tree.

#7136 #7187 #7184 #7185 #7192 #7138 #7139

with some changes and exclusions:
- all attempts to localize "fprintf(stderr,..." and "printf(..."
replaced by _untranslated_ "syslog(LOG_ERR ...";
- following *Translator.rdef files, that were not added in mentioned patches
were additionally created:
SGI, TIFF, RAW, RTF, PPM, WebP, EXR, STXT, WonderBrush, GIF, TGA;
- some small fixes for consistent catalogs building.

Thank you, Jorma! Please check. ;-)
