[netdata] enhance FindContext() methods and Lowpan::Context (#11836)

Browse Source 
This commit enhances the `FindContext()` methods and converts the
`Lowpan::Context` struct into a class.

The `FindContext()` methods are updated as follows:
- Renamed to `FindContextForAddress()` and `FindContextForId()` to
  more accurately reflect their function.
- The return type is changed from `Error` to `void`. Success is now
  indicated by checking the `IsValid()` state of the output `Context`
  object (matching how `Lowpan` class uses the `Context`). This
  change simplifies the callers and harmonizes the context check
  across different modules.

The `Lowpan::Context` struct is converted into a class, encapsulating
its members by making them private and introducing public getters.
