LibGfx/PortableFormat: Simplify read_number
signature
The function signature goes from: `bool read_number(Streamer& streamer, TValue* value)` to `ErrorOr<u16> read_number(Streamer& streamer)` It allows us to, on one hand use `ErrorOr` for error propagation, removing an out parameter in the meantime, and on the other hand remove the useless template.
