Add parsedModules optional parameter to build function

[jeshecdom]

We need to add parseModules optional parameter to build, like this:

export async function build(args: {
    config: Project;
    project: VirtualFileSystem;
    stdlib: string | VirtualFileSystem;
    logger?: ILogger;
    parser?: Parser;
    ast?: FactoryAst;
    parsedModules?: AstModule[]   <------- new optional parameter
}):

and then pass it to the precompile function as is.

We need to do this in order to avoid copying the code of build for compiling autogenerated ASTs. Copying the code of build can lead to bugs due to accidental omissions while copying or modifying (as I recently experienced in PR #2083). Also, code duplication can lead to unsynchronized code in different parts of the codebase.

Correct. Then, we need to extract the current code of build in an auxiliary function, and add two public accesses to it: one without parsedModules and one with it.

For the moment, keep the copied build function. See comment #2344 (comment).
