[PATCH v2 1/1] BaseTools/tools_def: Add GCC49xASL Toolchain support

[Chris Co <Christopher.Co@microsoft.com>]

From: Chris Co <chrco@microsoft.com>

This patch adds a build option for invoking GCC49 ARM cross
compiler in the Windows environment to build firmware for
Windows 10 IoT devices using NXP i.MX6 and i.MX7 SoCs.

In addition, this build option targets the Microsoft ASL
compiler instead of iasl.  The Microsoft ASL compiler is
necessary to expose Windows-specific Pin Function Config
Descriptors on Windows IoT devices.
