BaseTools: Fixed metafile parser issues

Browse Source 
https://bugzilla.tianocore.org/show_bug.cgi?id=1406
This patch is going to fix the regressions that
is introduced by commit 2f818ed0fb

The internal array for storing the metadata info should be cached
so that the meta file is parsed only once in one build.
