Martin Atkins 1380154250 lang: Data methods now take context.Context
This caused a bunch of mechanical changes to callers, of course. Expression
evaluation is a very cross-cutting concern, so updating everything all at
once would be a lot and so this stops at a mostly-arbitrary point wiring
a bunch of callers to pass in contexts without changing anything that has
lots of callers.

We'll continue pulling on this thread in later commits.

// Data is an interface whose implementations can provide cty.Value
// representations of objects identified by referenceable addresses from
// the addrs package.
//
// This interface will grow each time a new type of reference is added, and so
// implementations outside of the OpenTofu codebases are not advised.
//
// Each method returns a suitable value and optionally some diagnostics. If the
// returned diagnostics contains errors then the type of the returned value is
// used to construct an unknown value of the same type which is then used in
// place of the requested object so that type checking can still proceed. In
// cases where it's not possible to even determine a suitable result type,
// cty.DynamicVal is returned along with errors describing the problem.
