authn: include trust domains from cacertificates in san validator

This CL includes the trust domains from the meshConfig caCertificates
in the SAN validator. Without this change, we need to completely
disable that validation with the PILOT_SKIP_VALIDATE_TRUST_DOMAIN env
var. Backported from: https://github.com/istio/istio/pull/43536.

istio: add metric for debouncing (#40523)

* istio: add metric for debouncing

This CL adds metric for the delay between a first config change
enters deboucing until the final merged push request is pushed into
the push queue. This time plus the proxy convergence time give us
an upper bound on the total delay between a config change and the
change is pushed to proxies.

Also increased the buckets since logging shows that the debounce time
is pretty long (more than 1 minute).

* istio: handle debounce time entirely in the debounce() function

To address comments in https://github.com/istio/istio/pull/40523,
we will record after push finishes inside the debounce function.
We can actually remove the DebounceStart field in the push context
as a result.

Also change the buckets as discussed in the PR.
