Describe the feature

Using the AWS SigV4a signature scheme it in the AWS SDK for .NET currently requires an extra NuGet dependency to the native aws-c-auth library. However, all the frameworks supported by V4 have the required elliptic curve cryptography APIs to implement SigV4a entirely in managed code.

Use Case

Eliminate optional dependency to native code and increase platform compatibility.

Proposed Solution

• AWS4aSigner class gets added.
• AWS4aSignerCRTWrapper class and all related APIs in AWSSDK.Core and AWSSDK.Extensions.CrtIntegration get deprecated.

Other Information

I have started an implementation on my machine, will open a PR soon.
