ARM support

[Feiryn]

I added ARM support for both ARM and Thumb modes.

The only part I'm not 100% sure of is the patch size.
I don't really know if 12 bytes is too large and can overwrite code outside of the patched function in some really specific cases, like a really small function that precedes the target function.

@Feiryn thanks for adding the ARM support! For 12 bytes patching size that is an issue should be handled by a sanitizing check to avoid undefined behavior. But for now since amd64 and aarch64 both have the same issue, I would not try to solve it in this PR. I have created an issue to track it: #95

I'll start to review the change soon. Probably next week. Thanks for the contribution!

@Feiryn I have drafted a beta release https://github.com/microsoft/injectorppforrust/releases/tag/v0.5.0-beta.1. The official release still needs quite some time for preparation. Hope this can unblock you.
