[reflection] Coop handles icalls in System.Reflection and System.RuntimeTypeHandle (#4217)

* [sre] Add typed coop handle declarations

* [reflection] Implement mono_reflection_get_token_handle

  Rewrite mono_reflection_get_token_checked to use it.

* [reflection] Use handles for ves_icall_reflection_get_token

  - Get rid of mono_reflection_get_token_checked
  - Rename mono_reflection_get_token_handle to mono_reflection_get_token_checked

* [reflection] Use handles for ves_icall_GetCurrentMethod

* [reflection] Use handles for ves_icall_System_Reflection_MethodBase_GetMethodFromHandleInternalType_native

* [reflection] Use handles for ves_icall_System_Reflection_Module_ResolveSignature

* [reflection] Use handles for ves_icall_System_Type_internal_from_name

* [reflection] Use handles for ves_icall_System_Type_internal_from_handle

* [runtime] Use coop handles for System.Object.GetType ()

* [reflection] Use handles for ves_icall_MonoField_GetParentType

* [reflection] Use handles for ves_icall_MonoField_ResolveType

* [reflection] Use handles for most icalls in System.RuntimeTypeHandle
