When the topmost stack configuration declares an ephemeral input variable,
its values must be provided separately for each of the plan and apply
phases.
Therefore here we extend the API to allow specifying input variable values
during the apply phase, and add rules to check whether all of the
apply-time-required input variables have been specified and whether any
non-ephemeral variables are either unspecified or re-specified with equal
values during the apply phase.
This also extends the FindStackConfigurationComponents response to include
more metadata about the input variables and output values so that a caller
can know which ones are ephemeral. The name of that RPC function had
already become a little too specific with the inclusion of embedded stack
information and is even moreso now; we might choose to rename it to
something more generic like "AnalyzeStackConfiguration" in future, but
that'd be a breaking change and therefore requires more coordination.

When handling root input variable values, we now consider unset and null
values to be equivalent to each other. This is consistent with how we
handle variables in embedded stacks, and very similar to how we handle
variable in the modules runtime with `nullable = false`.
One difference from the modules runtime case is that we do not prevent
a null default value for stack variables.
When evaluating a stack's root input variables, supplied by the caller,
we must apply any default values specified in the variable
configuration for variables with no specified value. This commit adds
this default fallback case, using NilVal as a marker indicating the lack
of a specified value.
If no default value exists for a variable, it is therefore required to
be supplied by the caller. This commit also reports a diagnostic error
in this case.
Components expect that check results will be round-tripped
through the plan in order to update unknown check results
during the apply. We hadn't wired this up for stack plans,
resulting in panics when the apply tries to update a check
status that doesn't exist.
