Remove duplication of XHPAST version in PHP and C code

Browse source 
Summary:
Depends on D21063. Ref T13492. Currently, XHPAST defines a version in both PHP code and C code, and they must be kept in sync.

Switch to a single definition in PHP, then carry it through the build pipeline into C.

Test Plan: Did a clean rebuild of XHPAST, saw a version number carried in from PHP. Ran "xhpast --version".

Maniphest Tasks: T13492
