Add chain invocation for $moduleInit(), $moduleStart(), and $configureInit() methods

[Thushara-Piyasekara]

Purpose

During the codegen phase we generate a set of functions for initializing modules and their ballerina constructs. As of now, these initializations are done using a flattened dependency list for each ballerina module.

Fixes #42367

Approach

Changed the $moduleInit() and $moduleStart() BIRFunction generation boilerplate to generate a invocations of $moduleInit() functions instead of <.init>() functions. The new method generation will be as follows,

Did the same change for generated $configureInit() methods inside $configurationMapper class.
