Changes:
* Renames 'full copy searchable snapshot' to 'fully mounted index.'
* Renames 'shared cache searchable snapshot' to 'partially mounted index.'
* Removes some unneeded cache setup instructions for the frozen tier. We added a default cache size with #71844.
* Remove frozen tier restriction for ESS
* Remove section from 'Use ES for time series data'

Removes the experimental status for the frozen tier / shared_cache searchable snapshots for the 7.13 release.
Also adapts docs that URL repositories are now supported in 7.13 for searchable snapshots.
This adds additional documentation for shared_cache searchable snapshots that are targeting the frozen tier:
- it generalizes the introduction section on searchable snapshots, mentioning that they come in two flavors now
as well as the relation to cold and frozen tiers,
- it expands the shared_cache section and
- it adds Cloud-specific instructions for getting started with the frozen tier

This commit adds the `data_frozen` node role as part of the formalization of data tiers. It also
adds the `"frozen"` phase to ILM, currently allowing the same actions as the existing cold phase.
The frozen phase is intended to be used for data even less frequently searched than the cold phase,
and will eventually be loosely tied to data using partial searchable snapshots (as oppposed to full
searchable snapshots in the cold phase).
Relates to #60848
Whether the cold tier can handle years depends a lot on the use case and
for instance our BWC guarantees. This would need to be part of a
specific sizing exercise, so in the spirit of not over-promising, the
description of the cold tier has been changed to not mention years.
This adds general overview documentation for data tiers,
the data tiers specific node roles, and their application in
ILM.
