www/webkit2-gtk: update to 2.46.3

[vishwin]

Summary

Consolidate, flavourise, update. USE_GCC because D35327.

SONAMEs/flavours:

• GTK3 + libsoup = libwebkit2gtk-4.0 (40)
• GTK3 + libsoup3 = libwebkit2gtk-4.1 (41)
• GTK4 + libsoup3 = libwebkitgtk-6.0 (60)

Switch net/remmina to the 4.1 API/flavour

Reported by: eduardo
PR: 275914

Test Plan

The "recommended" testing is by running www/epiphany. Compared to 2.42 and earlier attempted updates, it crashes instead of hangs (more specifically indefinite wait condition), which is an improvement. Need to test with an epiphany newer than 43, which is the last version to use the 4.1 (GTK3 + libsoup3) API.

Aloha @vishwin,

the patch is no longer applicable against HEAD. I rebased it, but can't update the patch here. So please update the Revision using this Patch: {F88967723}

The patch was done against 411c13e07f33.

Best,
Torsten

Just noticed, that the MOVED entries are wrong. Besides i forgot to update the dates, there is no 50 flavor. I guess it should be 60?

[vishwin]

rebase and fix MOVED

may need another once-over on PORTREVISION bumps due to intervening updates
