Option to only build certain dependencies

Expected Behavior

There sould be an posibility to build only certen Dependencies and not onyl all

Current Behavior

it is only possible to ignore some dependencies in dev mode

Context

• UI5 Module Version (output of ui5 --version when using the CLI): 1.2.1

Affected components (if known)

• ui5-builder
• ui5-server
• ui5-cli
• ui5-fs
• ui5-project
• ui5-logger

The originated problem is that we have a shim for @babel/polyfill

specVersion: "1.0"
kind: extension
type: project-shim
metadata:
    name: babel-polyfills
shims:
    configurations:
        "@babel/polyfill": # name as defined in package.json
            specVersion: "1.0"
            type: module # Use module type
            metadata:
                name: "babel-polyfills"
            resources:
                configuration:
                    paths:
                        /lib/babel/: "dist"

when building we want to build this shim but not all other dependencies. that way we could just zip the dist folder and upload that to the SAP Gateway

In https://github.com/SAP/ui5-builder/pull/380 @kristian contributed a low level API that might resolve some use cases related to this topic.

The question now is how we expose this on a CLI and/or ui5.yaml level. I have compiled the following proposal which combines a new ui5.yaml configuration with new CLI parameters to hopefully allow solving most use cases. Any feedback would be greatly appreciated.

Proposal

New ui5.yaml configuration builder.requiredProjects

As proposed earlier, all listed projects are always built when the project is being built.

This is useful for scenarios where a dependency is exclusively used by the project itself (no reuse) and can therefore be viewed as being a part of the project.

New CLI parameters --include-dependency, --include-dependency-regexp, --exclude-dependency, --exclude-dependency-regexp

Similar to the already existing --include-task/--exclude-task parameters, they can include or exclude dependencies from the build.

This can be used to craft custom builds where some dependencies might not be required or are already given by the environment.

--all will act as an alias for --include-dependency="*" (including all dependencies). Omitting it is an alias for --exclude-dependency="*" (excluding all dependencies).

The [...]-regexp= variants allow specifying a regex that will be matched with the metadata.name property of the projects. This allows to include or exclude groups of dependencies based on their namespace.
