Issue #8145: meson: generation of '*-enums.c' files. 

Our meson build system was not properly building the enums.c file,
because they are versionned.

I did a similar trick as what I did for the pdbgen, which is that I used
a wrapper script around the existing perl script, which sets proper
options and generate a stamp file in the end (which is considered by
meson as the actual custom target, not the C file since it is generated
in the source dir).

The most important part is that the stamp file is a generated header
source (not just a random text file) which is **included** by the
generated C file. This is what will force meson to regenerate the C file
if the header is updated, **then** build using this new version, not use
an outdated versionned version (which would make for hard to diagnose
bugs), through the indirection of the intermediate stamp header.

See #4201.

# This is a wrapper to the tools/gimp-mkenums perl script which:
# * sets a few common values;
# * updates the ${filebase}enums.c directly in the source directory in
# order for it to be versionned.
# * Create a no-op stamp-header file to be included by the resulting
# enums.c. The goal is to make sure that meson will trigger a rebuild
# of the enums.c generation before compiling, if the enums.h changed.
# See the explanation here:
# https://github.com/mesonbuild/meson/issues/10196#issuecomment-1080742592
