[JSC] Remove m_calleeSaveRegisters from CodeBlock::JITData and rename it to BaselineJITData
​https://bugs.webkit.org/show_bug.cgi?id=234555

Reviewed by Saam Barati.

This patch removes m_calleeSaveRegisters from CodeBlock::JITData, and moving it to each JITCode.
This is reasonable since m_calleeSaveRegisters information belongs to JITCode, not CodeBlock.
And in LLInt, Baseline, and DFG cases, m_calleeSaveRegisters is the same. So we do not have this
field in these JITCode. Only FTL can have m_calleeSaveRegisters.

By removing m_calleeSaveRegisters from CodeBlock::JITData, now it only includes Baseline JIT related
data. So this patch renames CodeBlock::JITData to BaselineJITData.

We also use TrailingArray for BaselineJITData so that we can remove one level indirection when loading
JITConstantPool from JITData.
