Fix T59143: Frame Selected Doesn't work in hair particle editmode

This is caused by rBeb521b22b2b1.

Looks like `PE_minmax` doesnt play nice with the evaluated view_layer.
If we look inside `PE_get_current`, then `BKE_ptcache_ids_from_object`
will actually return a list of `PTCacheID` for the evaluated object.
However, looking further, then `PTCacheEdit` / `psys->pointcache->edit`
is always NULL for the evaluated object.

Without a valid `PTCacheEdit`, `PE_minmax` will basically do nothing.
So now we are passing the non-evaluated view layer in the case of
particles.

Regarding to @sergey, in a longer term we should probably make it so
evaluated pointcache have pointer to edit.
