webkit2gtk: update to 2.44.2

[chrysos349]

[ci skip]

I've been testing this for about a week now (as a part of gnome-46.0). So far everything works.

NOTES: See "What's new in 2.44"

• -DUSE_GTK4 is used by default now.
• -DUSE_WPE_RENDERER (and related deps) has been removed.
• OpenJPEG is no longer a dep, because support for the JPEG2000 image format has been removed.
• disable-dmabuf-nvidia.patch and fix-ftbfs-i386.patch have been removed because they has been merged into webkit.

Testing the changes

• I tested the changes in this PR: YES
