Fortran: Fix rejecting class arrays of different ranks as storage association argument and add un/pack_class. [PR96992]

Removing the assert in trans-expr, lead to initial strides not set
which is now fixed.  When the array needs repacking, this is done for
class arrays now, too.

Packing class arrays was done using the regular internal pack
function in the past.  But that does not use the vptr's copy
function and breaks OOP paradigms (e.g. deep copy).  The new
un-/pack_class functions use the vptr's copy functionality to
implement OOP paradigms correctly.

The recent move of libgfortran object files to subdirs and the resulting
breakage of libgfortran.so symbol exports demonstrated how fragile
deriving object and archive names from their libtool counterparts in the
Makefiles is.  Therefore, this patch moves that step into
make_sunver.pl, considerably simplifying the Makefile rules to create
the version scripts.

Bootstrapped without regressions on i386-pc-solaris2.11 and
sparc-sun-solaris2.11, verifying that the version scripts are identical
except for the input filenames.

With the change in subdirectories, the code for libgfortran fat libraries
needs to be adjusted to explicitly reference the subdirectory.  AIX
creates fat library archives and the compiler itself can be built as
either 32 bit or 64 bit application and default code generation.  For
the two, alternate versions of the compiler to interoperate, GCC needs
to construct the fat libraries manually.

The Makefile fragment had been trying to leverage as much of the existing
targets and macros as possible.  With the subdirectory change, the
location of single.o is more obscured and cannot be determined without
libtool.  This patch references the location of the real object file
more explicitly.

Utilizing subst seems like overkill and unnecessary obscuration for a single
object file.  Either way, it's digging below the libtool abstraction layer.

This also fixes Fortran bootstrap on AIX.

The move of libgfortran objects to subdirectories completely broke the
creation of libgfortran.so on Solaris.  Since the gfortran.ver-sun rule
doesn't support that structure, no libtool objects are found, thus no
symbols exported from libgfortran.so, causing every link to fail.

This patch fixes this by allowing for the new structure.

Tested on i386-pc-solaris2.11 and sparc-sun-solaris2.11.

The fallback function (gf_vsnprintf) to provide a vsnprintf function
if the system library doesn't have one would not compile due to the
variable name for the string's destination buffer not being updated
after the refactor in 2018 in edaaef60.

This updates the internal logic of gf_vsnprintf to now use the str
variable defined in the function signature.

Like in r12-7519-g027e30414492d50feb2854aff38227b14300dc4b, I've done
git grep -v 'long long\|optab optab\|template template\|double double' | grep ' \([a-zA-Z]\+\) \1 '

This is just part of the changes, mostly for non-gcc directories.
I'll try to get to the rest soon.  Obviously, the above command also
finds cases which are correct as is and shouldn't be changed, so one
needs to manually inspect everything.

I'd hope most of it is pretty obvious, but the config/ and libstdc++-v3/
hunks include a tweak in a license wording, though other copies of the
similar license have the wording right.

The previous patch used snprintf to set the message
