app/vmalert: switch from table-driven tests to f-tests
This makes test code more clear and reduces the number of code lines by 500.
This also simplifies debugging tests. See https://itnext.io/f-tests-as-a-replacement-for-table-driven-tests-in-go-8814a8b19e9e

While at it, consistently use t.Fatal* instead of t.Error* across tests, since t.Error*
requires more boilerplate code, which can result in additional bugs inside tests.
While t.Error* allows writing logging errors for the same, this doesn't simplify fixing
broken tests most of the time.

This is a follow-up for a9525da8a4

app/vmalert: make TestGroupStart more reliable ()
There was a sleep statement in the test, waiting for Group
to perform a couple of evaluation. But looks like
it worked unreliable for some CI tests like the one below
https://github.com/VictoriaMetrics/VictoriaMetrics/actions/runs/8718213844/job/23915007958?pr=6115

This commit changes the sleep statement on a function that
waits for a specific number of evaluations. It should make this
test faster in general case, and more reliable for slow environemnts.

app/vmalert: follow-up after c9375cac5e
c9375cac5e

Descriptions were updated in attempt to make it more clear for readers,
re-phrasing and linking missing docs.

`eval_delay` was added to tests to verify it can be unmarshalled.

`eval_delay` is now applied before timestamp alignment to make it more predictable.
Before, if delay < interval the timestamp won't be aligned.

`eval_delay` and `eval_offset` was added to API output.

`PreviouslySentSeriesToRW` converted to private `previouslySentSeriesToRW`.
