Instead of assuming that the WebDriver binary is in PATH or the two
most common build directories for our scripts, add a command line
argument to the script to pass a WebDriver binary.
We should be documenting required pacakges elsewhere and installing them
in the setup step of CI.
This also fixes a problem where the run script would fail if you already
had a cloned wpt directory.
Since both the WebDriver and Browser API are currently unstable during
WPT tests, it's a good idea to make sure that WPT passes even if there
are unexpected results. This will help avoid having failures marked as
red in the CI system caused by flaky WPT tests.
Introduce very initial and basic support for running Web Platform Tests
for Ladybird. This change includes simple bash script that currently
works only on Debian and could run tests with patched runner.
For now script to run WPT is not integrated in CI.
There is also a bunch of metadata required to run WPT. To avoid
introducing thousands of files in the initial commit for now it is
limited to run only css/CSS2/floats tests subdirectory.
