Reduce indirect function calls (#24980)

* Reduce indirect dispatch in hot paths in metadata

* Remove allocation indirections in utilcode for coreclr
- we no longer have a multi-dll distribution of code that needs to share heaps

* Remove unused code in GetCLRFunction

* Remove virtual dispatch around impl/decl methodtable access in MethodData
