Xmake adds Vala, Metal support and lockfiles

""" People often ask me what is special about XMake and what are the advantages compared to existing build tools such as CMake and Meson. Why should I use XMake instead of CMake?

Let me talk about the features and advantages first, XMake has the following points:

   - Concise and easy-to-learn configuration syntax, non-DSL
   - Powerful package management, support semantic version, toolchain management
  - Lightweight enough, no dependence
  -  Fast, the build speed is as fast as Ninja
  - Simple and convenient multi-platform and toolchain switching
  - Complete plugin system
  - Flexible build rules

"""

Personally, I just love that it's not another DSL to learn
