[EE-IR] Support Local Functions

This commit introduces support for calling and referencing local functions and
objects in evaluate expression on the IR backend.

The primary incision is a lowering inserted after Local Declaration Lowering,
that uses the intermediate data structures recorded by LDL to rewrite calls to
local functions to the appropriate function in the binary, instead of predicting
the compilation strategy. The required changes to the rest of the pipeline
facilitate piping the required data around.

The key to this transformation is that _captures by the local function_ must be
introduced as _captures by the fragment function_, such that the evaluator
infrastructure can find the appropriate values at run-time. This is necessary
due to the strategy of compiling local functions to static functions instead of
closures.

Additional test coverage of stepping behavior support the corresponding changes
in the Evaluator, part of the Kotlin Debugger plug-in.
