Add a new section to the llext documentation that explains how to debug
extensions and how to address the issues that may arise when doing so.

Some ARC processor configurations have separate memory for code (ICCM)
and for data (DCCM). Such configurations are unsuitable for LLEXT,
except for some quite special cases. For now, disable LLEXT and its
tests for these devices completely.

Adds compiler flag(s) and some architecture-specific relocations
for ARC. No userspace support, doesn't support all relocations.

This commit introduces architecture-specific ELF relocations for RISC-V,
in accordance with the RISC-V PSABI specification:
https://github.com/riscv-non-isa/riscv-elf-psabi-doc/blob/master/riscv-elf.adoc
Also, the necessary compiler configurations for compiling LLEXT
extensions on RISC-V are added, and the llext tests are executed on
RISC-V targets.
Calling llext extensions from user threads in RISC-V is still
unsupported as of this commit.

Fixes bad usage of single backticks in lieu of double backticks for
rendering inline literals, or simple '*' for italics.
When appropriate, a better construct than double backticks has been
selected (ex. :file:, :kconfig:option:, :c:func:, ...), or proper :ref:
have been used if the original intention was to have a link.

Adds support for all relocation type produced by GCC
on AARCH64 platform using partial linking (-r flag) or
shared link (-fpic and -shared flag).

Add documentation for the new LLEXT APIs that allow to call the
initialization and cleanup functions of an extension.

This patch improves the documentation for the llext subsystem, adding
information onhow to configure the llext subsystem, how to build
extensions using the Zephyr build system, and how to load and use these
in a Zephyr application.

The existing index.rst file contains a mix of information about the
llext subsystem and the LLEXT Extension Development Kit (EDK). This
commit splits the existing text into two separate files, index.rst and
build.rst, as a first step on improving the documentation.
No change in text is done in this commit.
