Add new Azure Pipeline definitions to build and run ArmVirtPkg with:
  * Ubuntu GCC5
Add PyTool based build of ArmVirtPkg
Add extdep for managing the iasl dependency
Add ArmVirtPkg.ci.yaml for Core CI
Add ReadMe.rst for status, details, and instructions

+
+**NOTE:** Do *not* follow the EDK II Compile Tools and Build instructions, see below...
+
+Differences from EDK Classic Build Setup
+````````````````````````````````````````
+
+- Build BaseTools using `python BaseTools/Edk2ToolsBuild.py [-t <ToolChainTag>]`
+
+  - This replaces `edksetup Rebuild`" from the classic build system
+
+- **No Action:** edksetup, Submodule initialization and manual installation of NASM and iASL are **not**
+  required, it is handled by the Pytools build system.
+
+Building with Pytools for ArmVirtPkg
+````````````````````````````````````
+
+* Install Pytools
+
+  .. code-block:: bash
+
+    pip install --upgrade -r pip-requirements.txt
+
+* Initialize & Update Submodules
+
+  .. code-block:: bash
+
+    stuart_setup -c ArmVirtPkg/PlatformCI/PlatformBuild.py TOOL_CHAIN_TAG=<TOOL_CHAIN_TAG> -a <TARGET_ARCH>
+
+* Initialize & Update Dependencies (e.g. iASL & NASM)
+
+  .. code-block:: bash
+
+    stuart_update -c ArmVirtPkg/PlatformCI/PlatformBuild.py TOOL_CHAIN_TAG=<TOOL_CHAIN_TAG> -a <TARGET_ARCH>
+
+* Compile
+
+  .. code-block:: bash
+
+    stuart_build -c ArmVirtPkg/PlatformCI/PlatformBuild.py TOOL_CHAIN_TAG=<TOOL_CHAIN_TAG> -a <TARGET_ARCH>
+
+* Running Emulator
+
+  - You can add `--FlashRom` to the end of your build command and the emulator will run after the build is complete.
+  - or use the `--FlashOnly` feature to just run the emulator.
+
+  .. code-block:: bash
+
+    stuart_build -c ArmVirtPkg/PlatformCI/PlatformBuild.py TOOL_CHAIN_TAG=<TOOL_CHAIN_TAG> -a <TARGET_ARCH> --FlashOnly
+
+Notes
+`````
+
+1. Including the expected build architecture and toolchain to the *stuart_update* command is critical. This is because there
+   are extra scopes and tools that will be resolved during the update step that need to match your build step.
+2. Configuring *ACTIVE_PLATFORM* and *TARGET_ARCH* in Conf/target.txt is *not* required. This environment is set by
+   PlatformBuild.py based upon the `[-a <TARGET_ARCH>]` parameter.
+3. QEMU must be on your path.  On Windows this is a manual process and not part of the QEMU installer.
+
+**NOTE:** Logging the execution output will be in the normal stuart log as well as to your console.
+
+Custom Build Options
+````````````````````
+
+**MAKE_STARTUP_NSH=TRUE** will output a *startup.nsh* file to the location mapped as fs0. This is used in CI in combination
+with the `--FlashOnly` feature to run QEMU to the UEFI shell and then execute the contents of startup.nsh.
+
+**QEMU_HEADLESS=TRUE** Since CI servers run headless QEMU must be told to run with no display otherwise an error occurs.
+Locally you don't need to set this.
+
+Passing Build Defines
+`````````````````````
+To pass build defines through stuart_build, prepend `BLD_*_` to the define name and pass it on the commandline. stuart_build currently
+requires values to be assigned, so add a `=1` suffix for bare defines.
+For example, to enable TPM2 support, instead of the traditional "-D TPM2_ENABLE=TRUE", the stuart_build command-line would be:
+
+.. code-block:: bash
+
+  stuart_build -c ArmVirtPkg/PlatformCI/PlatformBuild.py BLD_*_TPM2_ENABLE=TRUE
