  [JSC] Make scratch GPR / FPR static constexpr variables in WasmBBQJIT
https://bugs.webkit.org/show_bug.cgi?id=253754
rdar://106586236

Reviewed by Mark Lam.

This patch adds wasmScratchGPR and wasmScratchFPR static constexpr variables in WasmBBQJIT.
And remove m_scratchGPR / m_scratchFPR. So we can statically define and use these scratch registers.

We also
1. change m_shiftRCX to shiftRCX.
2. use FPRReg / GPRReg instead of RegisterID / FPRegisterID consistently.
