Hello world from the tests is no longer what it once was, a simple
hello_world function that prints. The sample was here to let people
explore and learn about how LLEXT and ELFs work.
Moving the sample extension code to the shell loader sample disconnects
the two and lets the sample remain simpler.
We use the new CONFIG_LLEXT_IMPORT_ALL_GLOBALS to show how to build
an extension with and without the Zephyr build system.

Reduce the heap and stack sizes needed for the shell loader sample app
so more devices may try it out.
Tried on a mimxrt1010_evk and noted the total ram usage was
approximately 44000 bytes. Prior to this change the mimxrt1010_evk was
unable to run the sample as the bss section overflowed the ram size.

Adds a sample application that can be used for trying out llext
with the shell. The docs cover how to load a hello world ELF
on to the device, assuming its an arm v7 architecture.
