build, win: teach GYP MSVS generator about MARMASM Items

The toolchain for ARM64 Windows includes support for assembly code, but
with a very different syntax from MASM and NASM. This change teaches
GYP how to emit the right XML tags in VCXPROJ files to support
compiling assembly files with the new tool.
