This rewrites `timestampInSeconds` to avoid side effects.

As a part of this, I also streamlined this a bit to remove special
handling for missing `timeOrigin`. If that is missing, we just fall back
to using `dateTimestampInSeconds`, instead of doing some custom handling
of `timeOrigin` - IMHO that should not be any less accurate, as
otherwise we are currently mixing `performance.now` with `Date.now()`
which is likely not necessarily accurate either.

[Gitflow] Merge master into develop

Today the logger export from core has a side effect and reads from the global.

This PR rewrites this to instead only keep the enabled flag on the
carrier. The logger itself is a "normal" method that just looks at the
carrier to see if logging is enabled or not.

ref #16804

This was addressed with
#16806, but we didn't
guard every location that uses `entry.nextHopProtocol`.

Will backport to v9 after merge.

We need to publish this package!

ref #16901

This PR introduces a `debug` function that aims to replace `logger`.

This gives us a couple of benefits:
1. communicates intent of the export much better
1. avoids collision with `logger` exported from other sdks (which is
used for sentry structured logging)
1. we can move structured logging `logger` code into `@sentry/core`,
reducing duplication across our sdks

We don't deprecate `logger` just yet, we need to convert everything else
in the other SDKs first.

…te (#16866)

Refactor our CLS and LCP tracking and recording logic. We now
have a `listenForWebVitalReportEvents` helper function which listens to
page hides and navigation span starts and ensures that the standalone
span logic is only called once per web vital. Previously, we had this
logic in the CLS and LCP function and it was quite a lot of duplicated
and identical code.

Apart of directly vendored code, we should avoid `enum`, as it has
bundle size impact.
