add FeeManager to pallet xcm (#5363)

Closes #2082

change send xcm to use `FeeManager` to assert if the sender should be
charged.

 I had to change the `FeeManager` of the penpal config to
ensure the same test behaviour as before. For the other tests, I'm using
the `FeeManager` from the `xcm::executor::FeeManager` as this one is
used to check if the fee can be waived on the charge fees method. Can I
assume that using the `xcm::executor::FeeManager` we are going to ensure
the same behaviour as before or should I also add some other
configuration to the `WaivedLocations` of other configs?
