Try to detect geometry type if unknown from DescribeFeatureType for WFS 1.0

[pathmapper]

Using the same logic as for WFS >= 1.1., but only when we do not know the exact geometry type from DescribeFeatureType.

A test was added.

Fixes #50935

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-release-3_28 release-3_28
# Navigate to the new working tree
cd .worktrees/backport-release-3_28
# Create a new branch
git switch --create backport-50943-to-release-3_28
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick b9409e1f9cb995f7c05acb4b76ec84ee12ffac49
# Push it to GitHub
git push --set-upstream origin backport-50943-to-release-3_28
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release-3_28

Then, create a pull request where the base branch is release-3_28 and the compare/head branch is backport-50943-to-release-3_28.
