llext: Linkable loadable extensions Adds the linkable loadable extensions (llext) subsystem which provides functionality for reading, parsing, and linking ELF encoded executable code into a managed extension to the running elf base image. A loader interface, and default buffer loader implementation, make available to the llext subsystem the elf data. A simple management API provide the ability to load and unload extensions as needed. A shell interface for extension loading and unloading makes it easy to try. Adds initial support for armv7 thumb built elfs with very specific compiler flags.

llext: refact: move ELF loading and linking to separate files This commit moves ELF loading and linking code to separate files. This is done to make the code more manageable and to make it easier to add new features in the future. No functional changes are introduced by this commit, except for a few static functions now made public to allow this file split to occur. Signed-off-by: Luca Burelli <l.burelli@arduino.cc>
