MdePkg/GoogleTest: Add HASH2 Protocol mock interface (#630)

# Preface

## Description

Adds the HASH2 Protocol to the Mock library implementation

For each item, place an "x" in between `[` and `]` if true. Example:
`[x]`.
_(you can also check items in the GitHub UI)_

- [ ] Impacts functionality?
  - Adds Hash2 to the Mock library for Unit Testing
- [ ] Impacts security?
- [ ] Breaking change?
  - no
- [ ] Includes tests?
- [ ] Includes documentation?

## How This Was Tested

Currently private unit tests that depend on these hash2 protocols

## Integration Instructions
