Port generator to use AsmResolver

[ds5678]

I have verified this to be consistent with the prior Cecil implementation, with a few exceptions:

• Unstripping has been improved in some cases.
• The AsmResolver-based HasOverrides is more accurate than the Cecil one, which causes some additional virtual methods and properties to be culled.
  • This has some minor side effects like slightly changing the content of static constructors in the declaring types of the newly culled methods.
• The Cecil implementation had some (rare) bugs in regards to generic parameters, which have been resolved in the AsmResolver implementation.
  • For example, sometimes generic method parameters were generated as generic type parameters in method body content.
  • In The Long Dark Assembly-CSharp.dll, there are only 45 differing methods, out of 104,874 total methods.

After doing some more validation, I discovered that the Cecil HasOverrides property was always returning false. In light of that, I have removed the HasOverrides check entirely. The output is now almost exactly consistent.

@SamboyCoding Thank you for the review! I'll address these tonight.

Thanks again for the review. I made some changes based on your feedback.

Note: my latest commit "broke" consistency due to changing the corlib, which caused a ton of imported references to become inequal, but otherwise it's still consistent.
