feat: Stream sync context is now available to all instances methods as a Stream.context attribute

[edgarrmondragon]

Some context on the design here:

• Adding a context parameter to RESTStream.get_new_paginator is a breaking change. It could be handled by catching a TypeError and retrying the call without the parameter, but this feels unnecessarily complicated.
• I opted for adding a new context attribute to the Stream instance. It's only set when the sync starts and is wrapped by MappingProxyType to discourage mutating the context object.
• The above makes the context parameter accepted by some methods a bit redundant, but I'm unsure whether it's worth deprecating and eventually removing it.
