  [JSC] Remove Wasm::PinnedRegisterInfo
https://bugs.webkit.org/show_bug.cgi?id=250920
rdar://104496000

Reviewed by Mark Lam.

This patch removes Wasm::PinnedRegisterInfo since we no longer have TLS version.
So, these register information can be defined at compile time. We should just define them in GPRInfo,
easy to read what is specified in each architecture.
