Consistently disallow `:static_parameter` in argument position (#61536)

Undo https://github.com/JuliaLang/julia/pull/61511, and clean up flisp
and IR validator cases where we previously considered this valid.

JL should now recognize `static_parameter` as a lowering input. Both
lowering implementations should now outline `static_parameter`
unconditionally.
