Placing the 2 fields used to call a delegate makes it less likely to split cache lines and makes every delegate call on arm64 smaller due to it being able to use
ldp.Diffs are here for x64 and here for arm64.
I'm planning to do a similar change for CoreCLR after #99200.
cc @MichalStrehovsky this was the arm64 size reduction I mentioned on Discord.
