Description

Like the base theme system, we are now able to create a sub-profile in order to inherit the dependencies and functionalities of a base profile. This would allow multiple profiles to share common modules, themes and configurations with minimal override/customization on individual sites.

Example 
name: My Profile
type: profile
description: 'My install profile.'
core_version_requirement: '^9.2'

base profile: standard

This also allows organizations to distribute a base profile with custom modules or themes included and sub-profiles can have access to those modules as any the sub-profile brings along.

Given the following:

docroot
  - profiles
    - base_custom_profile
      -modules
        - base_custom_module
          - base_custom_module.info.yml
      - themes
        - base_custom_theme
          - base_custom_theme.info.yml
    - sub_custom_profile
      - sub_custom_profile.info.yml (declares "base profile: base_custom_profile")
      - themes
        - sub_custom_theme
          - sub_custom_theme.info.yml (declares "base theme: base_custom_theme")

A site installed with "sub_custom_profile" will see "base_custom_profile" installed in its extension list and will be able to enable "base_custom_module". Its theme "sub_custom_theme" will also be able to inherit templates and libraries from its base theme "base_custom_theme" .
