UnitTestFrameworkPkg/Library: Add library instances

https://bugzilla.tianocore.org/show_bug.cgi?id=2505

Add the following library instances that are used to
build unit tests for host and target environments.

* CmockaLib with cmocka submodule to:

  https://git.cryptomilk.org/projects/cmocka.git

* DebugLibPosix - Instance of DebugLib based on POSIX
  APIs (e.g. printf).
* MemoryAllocationLibPosix - Instance of MemoryAllocationLib
  based on POSIX APIs (e.g. malloc/free).
* UnitTestBootLibNull - Null instance of the UnitTestBootLib
* UnitTestBootLibUsbClass - UnitTestBootLib instances that
  supports setting boot next to a USB device.
* UnitTestLib - UnitTestLib instance that is designed to work
  with PEI, DXE, SMM, and UEFI Shell target environments.
* UnitTestLibCmocka - UintTestLib instance that uses cmocka
  APIs and can only be use in a host environment.
* UnitTestPersistenceLibNull - Null instance of the
  UnitTestPersistenceLib
* UnitTestPersistenceLibSimpleFileSystem - UnitTestPersistenceLib
  instance that can safe the unit test framework state to a
  media device that supports the UEFI Simple File System
  Protocol.
* UnitTestResultReportLibConOut - UnitTestResultReportLib
  instance that sends report results to the UEFI standard
  output console.
* UnitTestResultReportLibDebugLib - UnitTestResultReportLib
  instance that sends report results to a DebugLib using
  DEBUG() macros.
