Aliaksandr Kalenik d2528dd5ce LibWeb: Compare Screenshot tests directly against expected PNGs
Instead of rendering a reference HTML page that wraps an <img> tag
pointing to a PNG, Screenshot tests now load the expected PNG directly
from disk and compare it against the rendered screenshot. This
eliminates the indirection of loading and rendering a second page just
to display a static image.

This also means --rebaseline now works for Screenshot tests, generating
the expected PNG automatically instead of requiring manual screenshot
capture and placement.

Changes:
- Add TestMode::Screenshot with its own collector and runner
- Move PNGs from Screenshot/images/ to Screenshot/expected/ with
  normalized names matching input filenames
- Remove all 92 reference HTML wrapper files and the images/
  directory
- Remove <link rel="match"> from all 94 Screenshot input HTML
  files
- Update add_libweb_test.py Screenshot boilerplate accordingly
- Add Screenshot mode to results viewer image comparison tabs
