CSS Writing Modes: tests for `text-combine-upright` on fullwidth characters

This PR is a continuation from https://github.com/w3c/csswg-test/pull/558, which was once merged then reverted. I restored the original file and made following changes.

* add tests and reference to use vertical-rl per suggestion from editor.
* use text-combine-upright: all mainly where possible
* add tcu: all + tt: full-width case as 002 (former 002 is now 003)
