libcamera: yaml_parser: Replace ok flag to get() with std::optional
The YamlObject::get() function takes a default value and an optional bool ok flag to handle parsing errors. This ad-hoc mechanism complicates error handling in callers. A better API is possible by dropping the default value and ok flag and returning an std::optional. Not only does it simplify the calls, it also lets callers handle errors through the standard std::optional class instead of the current ad-hoc mechanism. Provide a get() wrapper around std::optional::value_or() to further simplify callers that don't need any specific error handling.
