Add half precision floating point support to StreamPeer

Browse Source 
Closes godotengine/godot-proposals#5983

Adds put/get methods to `StreamPeer` that handles half precision
floating point values.
Adds endode/decode half precision floating point to `marshalls`.
Adds `get_half` and `store_half` to `FileAccess`
