Subject: [PATCH 1/1] BaseTools: Fix DSC LibraryClass precedence rule

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3965

Currently DSC LibraryClass precedence rule is not align with DSC Spec.

The expectation rule should be:
[LibraryClasses.$(ARCH)] < [LibraryClasses.Common.$(MODULE_TYPE)]

The actual behavior is:
[LibraryClasses.$(ARCH)] > [LibraryClasses.Common.$(MODULE_TYPE)]

This patch fixes the issue.
