Josh Story 1f1f8eb559 [Float][Fizz][Fiber]: Refactor <style> Resource implementation to group on flush (#26280 )

There is a problem with <style> as resource. For css-in-js libs there
may be an very large number of these hoistables being created. The
number of style tags can grow quickly and to help reduce the prevalence
of this FIzz now aggregates all style tags for a given precedence into a
single tag. The client can 'hydrate' against these compound tags but
currently on the client insertions are done individually.

additionally drops the implementation where style tags are embedding in
a template for one where `media="not all"` is set. The idea is to have
the browser construct the underlying stylesheet eagerly which does not
happen if the tag is embedded in a template

Key Decision:
One choice made in this PR is that we flush style tags eagerly even if a
boundary is blocked that is the only thing that depends on that style
rule. The reason we are starting with this implementation is that it
allows a very condensed representation of the style resources. If we
tracked which rules were used in which boundaries we would need a style
resource for every rendered <style> tag. This could be problematic for
css-in-js libs that might render hundreds or thousands of style tags.
The tradeoff here is we slightly delay content reveal in some cases (we
send extra bytes) but we have fewer DOM tags and faster SSR runtime
