No need to introspect deprecated API, especially for the new non-C APIs
after a major version update.
This also sync both the autotools and meson-generated GIR files.
See also #4018.
More of the files were wrong, or at least not absolutely identical to
the files generated by the autotools. I am not doing any code change
other than trying to make both build systems produce identical files
(except for slight differences on 2 files not worth the effort) even
though maybe some things can be improved (especially on the include
list). Maybe to be improved later.
Also fixing 2 of the previously autotools-generated files because of
space typos which should have been committed earlier.
Finally it is to be noted that there is no logics to copy the generated
files back to the source directory in the meson rules. I am not sure
anyway this is really worth it and maybe we should just stop tracking
these generated files eventually.
This is listed twice and is not needed for libgimpui (not listed in
autotools build) and apparently it provokes introspection warnings on
MSYS2 builds.
Thanks to lillolollo and Massimo for debugging this.

Some stuff are still wrong, but this is a first step in the right
direction.
Add gimp_procedure_config_begin_export() and end_export() which
are wrappers around begin_run() and end_run() and additionally
pretty much completely manage GimpMetadata handling.
A GimpProcedureConfig can provide boolean properties "save-exif",
"save-xmp" etc. in order to have them automatically managed by
begin_export() and end_export(). This also restores the feature of
overriding the procedure's saved default values with export
preferences, but not the values from the last export, like it
used to be in 2.10.
Move gimp_image_metadata_save_prepare() and save_finish() (which are
now completely handled by GimpProcedureConfig) from libgimpui to
libgimp, but keep their declarations in the libgimpui header. Not
perfect, but not finished either.
Also fix gimp_image_metadata_save_prepare() to set the affected
GimpMetadataSaveFlags to 0 when the image has no metadata at all.
This is hopefully a temporary setback since we want to consider the
introspected API as a core feature (otherwise we'd end up with third
party builds deactivating the feature, and get a very random experience
depending on where you got GIMP) hence don't want it to be optional
(note that I haven't added a configure option).
Anyway for now, it seems that cross-building introspected data is not
really supported (or I'm still figuring it out).
Apart from some obvious typo, libgimpui link was failing with meson
because it now relies on a function from libgimpconfig (i.e.
gimp_config_reset()), since commit bfb7f43dbc. This fixes:
> /usr/bin/ld: libgimp/gimpproceduredialog.c:223: undefined reference to `gimp_config_reset'
