[JSC] Add convertUInt32ToDouble / convertUInt32ToFloat
https://bugs.webkit.org/show_bug.cgi?id=290905
rdar://148407575
Reviewed by Yijia Huang.
This patch adds convertUInt32ToDouble / convertUInt32ToFloat. They are
efficiently implemented in x64 and ARM64. We leverage this in both JS
and wasm. And we introduce ConvertUInt32ToDouble / ConvertUInt32ToFloat
lowering rule for ARM64.
