[PATCH] SourceLevelDebugPkg/DebugAgentCommon: Use global variable for revision

[Hao Wu <hao.a.wu@intel.com>]

Since some static code checkers complain that comparing two macros will
generate a constant result, this commit uses a global variable to
reflect the revision information of the debug agent, rather than using a
macro directly.
