  [AArch64] Remove unnecessary funnel shift sve costs.

D127680 added some unnecessary funnel shift costs for AArch64 to "match
the legacy behaviour". The default costs are closer to the correct
values and line up with the scalar/neon costs better. Remove the lines
again to clean up the code, they can be added back at a later date with
better values if needed.
