chore(cli): move crewai eval under experimental (#7707)

Nothing about the command changes. It is still `crewai eval`, still listed in
`--help`, still takes `--run`, still prints the same lines. Only the module
moved, from `crewai_cli/eval_crew.py` to `crewai_cli/experimental/eval_crew.py`,
with its tests alongside.

The package says what the command's location could not: its output and its
options may change between releases without the deprecation cycle a settled
command gets. That is honest about where it stands — most of what it depends
on lives outside this repository, in an AMP endpoint and the evaluator behind
it, and both are new enough that the report's shape is still moving. The
command is already built to absorb some of that, printing whatever the
evaluation graded rather than a list of its own, but the promise it makes to a
user should match.

`crewai/experimental/` has the same role on the library side, so this is the
convention the repository already has rather than a new one. The CLI had no
experimental package before; it does now, and `crewai eval` is its first
tenant.

+`crewai eval` is here because most of what it depends on lives outside this
