Validate the attributes CFDictionaryRef when decoding FontPlatformData classes

Reviewed by Alex Christensen.
This is the first dive into the expected key/values in the FontPlatformData

Like other IPC validation we've done, it's more robust (while being less
flexible) to rely on structs
that pull out values for serialization an deserialization.
