Dependency version bumps ahead of v8.10

This PR makes this repository more in line with build-win64-mxe by updating all dependencies to the latest version (where possible), improving the existing patches and adding some new patches for dependencies that cause failures during building. I tested the binaries on the libvips test suite and did not encounter any problems.

The only thing I came across is that --vips-config is currently returning incorrect information, for example:

$ vips.exe --vips-config
native win32: no, ...

PR https://github.com/libvips/libvips/pull/1708 should fix this.

The only differences between this repository and build-win64-mxe are (after merge):

No support for heifsave because libx265 is difficult to cross-compile and the resulting DLL is 18.9 MB.
No support for MAT file version 7.3, it requires the HDF5 library which is difficult to cross-compile (see the build and needed patches).
No NIfTI support.
Support for reading and writing AVIF images is missing, because aom isn't build.
No support for "semi-static" builds.
Optional support for MozJPEG is missing.
ARM/ARM64 cannot be used as build target.

Improvements

Use a dummy libintl implementation (see libvips/libvips#1637).

Update JHBuild to 3.36.0.
