This PR closes out the remaining tasks in #1918 by adding support for hot/cold splitting of EH funclets in the VM. This support requires the following changes:
ReadyToRunJitManager::JitCodeToMethodInfo, when searching the Scratch table for the corresponding hot MethodIndex of a given cold MethodIndex, we now handle MethodIndices of cold EH funclets that aren't in the table (i.e. when part of the main body is split).ReadyToRunJitManager::IsFuncletnow returns true for cold EH funclets that are in the Scratch table.
