Move PlaneLayout lookup to GraphicBuffer

This keeps GraphicBufferMapper's lock closer to a raw
lock avoiding the PlaneLayout query if nobody is asking for it,
reduces code duplication between Gralloc 4 & 5, and enables
caching of the PlaneLayout to minimize queries

Partial step towards an extended lock buffer API

Also begin modernizing the API surface using a proper
Result<T> along with an error enum class
