No, that would be a significant security violation (being in a position
to know anything about the state user's computer).

If a resource is configured, has HTTP headers, such that encourage it to
be cached client-side, and the server can determine that it is being
re-requested when it would otherwise be expected to be retrieved from
the cache, then they might decide that they have grounds for concluding
that the browser's cache is full (as the simplest (but a long way from
the only) explanation for why it was being re-requested).
However, the evidence available to them would not actually support that
conclusion, and the if they make such an announcement it would speak of
a comprehension defect in Google's programmers rather than the
availability of a technique for gauging when the cache is full. (A more
cautious announcement, along the lines of; "your browser appears to us
to be behaving as if its cache is full", would be a more realistic
assertion).

There is no valid solution. You cannot determine with certainty the
state of a web browser's cache with scripts, HTML (obviously, as it is a
mark-up language) or any server-side strategy, full stop.
