Add built-in vipsgen code generator (#496)

* Update README to reflect built-in code generator

Replace the "Project Status & Future" section that recommended the
external vipsgen project with a concise description of the built-in
code generator. Add a Code Generation section with regeneration
instructions. Update Go requirement from 1.16+ to 1.23+ to match
go.mod.

* Add built-in code generator and auto-generated libvips bindings

Add cmd/vipsgen, a code generator that uses libvips GObject
introspection to auto-generate type-safe Go/C bindings. This covers
193+ operations across 9 categories: arithmetic, colour, conversion,
convolution, create, freqfilt, histogram, morphology, and resample.

Hand-written bindings for operations now covered by the generator are
removed from arithmetic, conversion, convolution, create, morphology,
and resample. Complex operations (image I/O, draw, etc.) remain
hand-written. image.go is updated to call generated functions where
applicable.

Also adds golden test images for the current platform and updates
.gitignore to exclude the compiled vipsgen binary.

* Exclude sdf operation to fix build on older libvips

The sdf operation and VipsSdfShape enum were added in libvips 8.16,
but CI uses Ubuntu's libvips-dev which provides 8.12. Excluding sdf
from code generation fixes the build (192 ops, down from 193).

Also fix .gitignore to use /vipsgen so it only excludes the compiled
binary at the repo root, not the cmd/vipsgen/ source directory.

* Add vipsgen generator source files

The previous .gitignore entry for "vipsgen" inadvertently excluded the
cmd/vipsgen/ source directory. These files were missed in the initial
commit. Adds the generator, introspection, and template source files.
