Refactor the contruction of the manifest check inputs.

This is a no-op change for a majority of cases.

Before this change, the contruction of the manifest check inputs is
confusing. It mutates uses_libs properties in place just for the
manifest check, by replacing module names with library names for
direct dependencies and merging library names from CLC for both direct
denpendencies and transitive denpendencies, and then constructs manifest
check inputs from those mutated uses_libs properties. This is
error-prone and leads to insistency: the goal is to check that the CLC
matches the manifest, but the inputs to the check don't reflect the CLC.

After this change, we no longer mutate uses_libs properties in place.
Instead, we maintain a separate list of missing denpendencies, and then
construct manifest check inputs directly from the CLC for all existing
libraries, no matter they are direct or transtive, and from the separate
list of missing libraries. This change makes the logic more
consistent and straightforward, and it also allows us to easily do the
next change, which is to propagate transtive missing denpendencies.

In fact, this change revealed several bugs around library optionality
and order in CLC construction, and fixed them.
