meson: Add script to use VERSION file for getting version

Graphics / Mesa 3D Graphics Library / Mesa - Dylan Baker [pnwbakers.com] - 9 November 2017 19:19 EST

Meson has up until this point set it's version in the root meson.build script, while the other build systems read the VERSION file. This is just "one more thing" to duplicate between meson and every other build system. This script is a simple "read, strip, print" sort of deal to allow meson to read the VERSION file.

I chose to implement this in python since python is portable, and to keep the meson.build script clean. This is also complicated by the fact that the project() call *must* be the first non-comment,non-blank in the toplevel meson.build script.

v2: - Move from scripts/ to bin/- use python explicitly to run the scripts to support windows
