WPT: Upstream and add some transaction scheduling tests (#22027)

In service of w3c/IndexedDB#253 move some
transaction scheduling tests from Blink to WPT.

This involved converting them from js-test.js to testharness.js, but
the overall logic of each test was retained.

This also adds one new test which verifies the change described
in w3c/IndexedDB#319 - all browsers implicitly
block R-O transactions behind overlapping R/W transactions.
