Documentation: Rework docs.rst into introduction.rst

docs.rst is the landing page for the documentation from the libcamera
website, but isn't particularly introductory. Move much of the content
from guides/introduction.rst to docs.rst, which will serve as the new
introductory page. Remove guides/introduction.rst.

-Developers guide to libcamera
-=============================
-
-The Linux kernel handles multimedia devices through the 'Linux media' subsystem
-and provides a set of APIs (application programming interfaces) known
-collectively as V4L2 (`Video for Linux 2`_) and the `Media Controller`_ API
-which provide an interface to interact and control media devices.
-
-Included in this subsystem are drivers for camera sensors, CSI2 (Camera
-Serial Interface) receivers, and ISPs (Image Signal Processors)
-
-The usage of these drivers to provide a functioning camera stack is a
-responsibility that lies in userspace which is commonly implemented separately
-by vendors without a common architecture or API for application developers.
-
-libcamera provides a complete camera stack for Linux based systems to abstract
-functionality desired by camera application developers and process the
-configuration of hardware and image control algorithms required to obtain
-desirable results from the camera.

-In this developers guide the `Licensing`_ requirements of the project are
-detailed.
-
-This introduction is followed by a walkthrough tutorial to newcomers wishing to
-support a new platform with the `Pipeline Handler Writers Guide`_ and for those
-looking to make use of the libcamera native API an `Application Writers Guide`_
-provides a tutorial of the key APIs exposed by libcamera.

-Licensing
----------
-
-The libcamera core, is covered by the `LGPL-2.1-or-later`_ license. Pipeline
-Handlers are a part of the libcamera code base and need to be contributed
-upstream by device vendors. IPA modules included in libcamera are covered by a
-free software license, however third-parties may develop IPA modules outside of
-libcamera and distribute them under a closed-source license, provided they do
-not include source code from the libcamera project.
-
-The libcamera project itself contains multiple libraries, applications and
-utilities. Licenses are expressed through SPDX tags in text-based files that
-support comments, and through the .reuse/dep5 file otherwise. A copy of all
-licenses are stored in the LICENSES directory, and a full summary of the
-licensing used throughout the project can be found in the COPYING.rst document.
-
-Applications which link dynamically against libcamera and use only the public
-API are an independent work of the authors and have no license restrictions
-imposed upon them from libcamera.
