/**
 * Augments a TypeScript Compiler Host's resolveModuleNames function to collect dependencies
 * of the containing file passed to the resolveModuleNames function. This process assumes
 * that consumers of the Compiler Host will only call resolveModuleNames with modules that are
 * actually present in a containing file.
 * This process is a workaround for gathering a TypeScript SourceFile's dependencies as there
 * is no currently exposed public method to do so. A BuilderProgram does have a `getAllDependencies`
 * function. However, that function returns all transitive dependencies as well which can cause
 * excessive Webpack rebuilds.
 *
 * @param host The CompilerHost to augment.
 * @param dependencies A Map which will be used to store file dependencies.
 * @param moduleResolutionCache An optional resolution cache to use when the host resolves a module.
