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.

Reallocates a buffer of type EfiReservedMemoryType.
Allocates and zeros the number bytes specified by NewSize from memory of type

NewSize bytes are copied from OldBuffer to the newly allocated buffer, and
OldBuffer is freed. A pointer to the newly allocated buffer is returned.

enough memory remaining to satisfy the request, then NULL is returned.
