This is necessary due to the way we've factored the libraries imported
by users into modules. The primary alternative is to ensure that each
child module imports the root module for a package and registers itself
with that package where necessary to prevent circular dependencies. This
simplifies the core SDKs slightly at the cost of greater complications
in the generated SDKs; the approach taken by these changes seems like a
more maintainable option.

The langauge SDKs will use this function to fetch the state required to
deserialize a resource reference. SDK support will be added as a follow-up
change.
Contributes to #2430.
Resources are serialized as their URN, ID, and package version. Each
Pulumi package is expected to register itself with the SDK. The package
will be invoked to construct appropriate instances of rehydrated
resources. Packages are distinguished by their name and their version.
This is the foundation of cross-process resources.
Related to #2430.

Move these tests to a new package, `lifecycletest`, that also exposes
APIs that allow consumers to implement their own lifecycle tests. This
is intended to ease the burden of testing plugin implementations and to
set the stage for cleaning up the lifecycle tests themselves.
This involves two changes to the public API, only one of which is
strictly necessary:
- The `host` field of `UpdateOptions` is now exported
- The `Journal` type has been moved from test-only code to the package
proper
The former change is necessary, as it is the mechanism by which package
consumers may inject their own plugin loaders. I was reluctant to expose
this field originally because I wanted to ensure that the behavior of
packages that embed Pulumi is consistent with that of the Pulumi CLI
with respect to plugin loading. I now believe that the risk of consumers
changing this behavior outside of test scenarios is low enough that we
can expose this field. This may also be useful for future scenarios,
e.g. statically linking providers and Pulumi programs.
The latter change is not necessary, but fleshes out the engine package
into a more complete toolkit. Downstream consumers may use the Journal
type to conveniently implement snapshotting.
