ci: do not wait for generating int and e2e matrix (#15546)

Previously, this was the flow (`=>` means wait for previous step, `&`
means runs in parallel):

Changes & Build => int-matrix => tests-int
Changes & Build => e2e-matrix => e2e-prep => tests-e2e

This PR runs int and e2e matrix generation immediately and in parallel,
without having to wait for previous steps. Should save about 8 seconds.

**New flow:**

Changes & Build & int-matrix => tests-int
Changes & Build & e2e-matrix => e2e-prep => tests-e2e
