Rewrite SVC handler using source generators rather than IL emit (#3371)

Browse source 
* Implement syscall handlers using a source generator

* Copy FlushProcessDataCache implementation to Syscall since it was only implemented on Syscall32

* Fix wrong argument order in some syscalls

* Delete old Reflection.Emit based syscall handling code

* Improvements to the code generation

* ControlCodeMemory address and size is always 64-bit
