Christian Schwarz 32a12783fd pageserver: batching & concurrent IO: update binary-built-in defaults; reduce CI matrix (#11923) ...

Use the current production config for batching & concurrent IO.

Remove the permutation testing for unit tests from CI.
(The pageserver unit test matrix takes ~10min for debug builds).

Drive-by-fix use of `if cfg!(test)` inside crate `pageserver_api`.
It is ineffective for early-enabling new defaults for pageserver unit
tests only.
The reason is that the `test` cfg is only set for the crate under test
but not its dependencies.
So, `cargo test -p pageserver` will build `pageserver_api` with
`cfg!(test) == false`.
Resort to checking for feature flag `testing` instead, since all our
unit tests are run with `--feature testing`.
