[JSC] Use dup-element for Vector Float Splat in ARM64
https://bugs.webkit.org/show_bug.cgi?id=248841
Reviewed by Justin Michaud.
This patch implements vectorSplatFloat32 / vectorSplatFloat64 in ARM64 with
dup-element so that
we can enable them in AirOpcode, simplifying our implementation for Splat in
WasmAirIRGenerator.
