BaseTools:Add [packages] section in dsc file

BZ:https://bugzilla.tianocore.org/show_bug.cgi?id=2270

Currently a PCD (e.g. FeaturePCD) cannot be used in a conditional
statement in a DSC/FDF file without a module in the build referencing
the PCD package DEC file.

An example implementation that to support this is to allow a [Packages]
section in the DSC file to list additional package dependencies for PCD
references in the package DSC/FDF files.

this patch is going to  add the ability to have the [packages] section
defined in the DSC file
