doc: fix doxygen INPUT path; brand html output

Clean up the INPUT paths for doxygen scanning:

- directory scans include sub-directories so no need
  to include them explicitly
- remove excluded (legacy) includes that no longer exist

Sync directory changes in the CMakeLists.txt (as noted in the comments)

Add content to the home page of the doxygen-generated HTML, and add a
Zephyr branding theme.

# API Documentation {#index}
## Introduction
The Zephyr OS is a small-footprint kernel designed for use on
resource-constrained and embedded systems: from simple embedded
environmental sensors and LED wearables to sophisticated embedded
controllers, smart watches, and IoT wireless applications.
See the [zephyrproject.org](https://zephyrproject.org) site for more
information about the project and becoming a member, and this [summary
of Zephyr resources](https://docs.zephyrproject.org/latest/introduction/index.html#resources)
to help you find your way around the project.
## Supported Boards
The Zephyr kernel supports multiple architectures, including ARM
Cortex-M, Intel x86, ARC, NIOS II, Tensilica Xtensa, and RISC-V 32. For
details, see the [latest supported boards
documentation](https://docs.zephyrproject.org/latest/boards/index.html).
## Licensing
Zephyr is permissively licensed using the Apache 2.0 license (as found
in the [project's GitHub LICENSE
file](https://github.com/zephyrproject-rtos/zephyr/blob/master/LICENSE).
There are some imported or reused components of the Zephyr project that
use other licensing, as described in [Licensing of Zephyr Project
components](https://docs.zephyrproject.org/latest/LICENSING.html#zephyr-licensing).
