BaseTools: Remove CanSkip calling for incremental build

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2978

If a module add a new PCD, the pcd token number will be
reassigned. The new Pcd token number should be updated
to all module's autogen files. CanSkip can only detect a
single module's change but not others. CanSkip block the
pcd token number update in incremental build, so this
patch is going to remove this call.
