[fix] losing WFS DCP endpoints upon cloning WFS URI

[andreassteffens]

When the WFS datasource URI is cloned (e. g. when applying an additional filter to a WFS layer) Get/Post DCP endpoints which have been originally parsed from the capabilities document are lost and all WFS operations fall back to using the capabilities URL.

This commit introduces two new getters to the QgsWFSDataSourceURI class which are used to transfer the stored endpoint informationen to a new instance upon cloning.

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-queued_ltr_backports queued_ltr_backports
# Navigate to the new working tree
cd .worktrees/backport-queued_ltr_backports
# Create a new branch
git switch --create backport-52648-to-queued_ltr_backports
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 7aefbc15a7c1a9f35dfdad7e26d810228ea2276e,c50f78488b4dce62fbbd3b037abdf6670dd4d489,ab13ece4dc175f67b8a7203869c2aecb5e0a467a
# Push it to GitHub
git push --set-upstream origin backport-52648-to-queued_ltr_backports
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-queued_ltr_backports

Then, create a pull request where the base branch is queued_ltr_backports and the compare/head branch is backport-52648-to-queued_ltr_backports.
