Add MacroAssembler::patchableBranch64 and fix ARM64's patchableBranchPtr
​https://bugs.webkit.org/show_bug.cgi?id=147761

Reviewed by Mark Lam.

This patch implements MacroAssembler::patchableBranch64 in 64bit environments.
And fix the existing MacroAssemblerARM64::patchableBranchPtr, before this patch,
it truncates the immediate pointer into the 32bit immediate.
And use patchableBranch64 in the baseline JIT under the JSVALUE64 configuration.
