Increase parallelism on Linux WPT testing
The time taken by each chunk is uneven, with WPT-1 the longest before this change at 30 ~ 45 minutes. This reduces it to 15 ~ 20 minutes.
Surprisingly, increasing the number of processes seems to also make `test_element_in_collection` in `/webdriver/tests/execute_script/cyclic.py` **unexpectedly pass**. This happened reliably in three different runs:

Enable some mach commands to be run with python3
This change finally enable the following commands to be run with python3:
* `build`
* `test-unit`
* `package`
As previously explained, `test-tidy` will require more work in the wpt repository directly. Maybe `test-tidy --no-wpt` is achievable relatively quickly though.
For possible remaining bits that might need to be worked on, see https://github.com/servo/servo/issues/23607

Also reduces the number of WPT chunks since per-task overhead becomes more siginificant when tasks are becoming shorter.
