public access for fd proto builder

[jhsenjaliya]

both mFileDescSetBuilder and mFileDescSetBuilder is useful to be accessible too make use of it in other methods. I already have use for mFileDescProtoBuilder.
would it be possible to make it public ?

[jhsenjaliya]

or if we can make the constructor public, user can also create the DynamicSchema using FileDescriptor directly.
@os72 pls let me know ur thoughts.
THanks
