Common client code and few bug fixes

[hpya93]

Hi @jhand2

Have added

• Files: abi.go, client.go: Code to issue RotateContextHandle, DeriveChild, ExtendTCI and Sign commands
• File- sign.rs: Bug fix for IS_SYMMETRIC flag in sign.rs file
• File- sign.rs: Bug fix for DPE error code in sign.rs. It must be "ArgumentNotSupported" instead of "InvalidArgument" when DPE profile does not support a command flag.
• File - CertifyKey.go, TagTci.go: Bug fix, the context handle created for Simulation mode is not used in code. The contexthandle is stored in variable "handle", but variable "ctx" is used
• File - InitializeContext.go: Separated out code for simulated context handle creation and put it as a func in InitializeContext.go file. This block was repeated many times.
• Files - negativeCases.go, simulator.go, verification.go: Added a negativeCases.go - it will test InvalidHandle, wrongLocality, Unsupported DPE command, Unsupported command flags. Tried to address your comment in TagTCI PR by writing a separate function for checking WrongLocality and other negative cases..

When this is merged I shall change other PRs in tune to the main branch with these changes. Kindly let us know the comments.
