Support injecting anything
* Nested types
* Events
* Properties
* Assemblies

Support additional metadata in injected assemblies

Make setter for TypeAnalysisContext::OverrideBaseType public

TypeAnalysisContext::InterfaceContexts as list rather than array

Fix sign bug

Support generic parameters on type contexts and method contexts

Make GenericParameterTypeAnalysisContext instances unique

Revert change to Il2CppGenericParameter::Index

Use attributes to determine if injected methods are static
* Also add hide by sig attribute for injected constructors

Support overrides on injected methods

In ControlFlowGraphOutputFormat, exclude injected assemblies

Ensure injected assemblies can't delete existing assemblies

Backing field on .NET Standard for injected method overrides
