Use section offset from the section header in
llext_manager_load_data_from_storage() to simplify calculations and
eliminate a function parameter.

file_offset in struct lib_manager_segment_desc is unused, remove it.

We don't need to store .bss address and size until the module is
freed since .bss is allocated together with .data and we only need
its size when initialising it, not when freeing module memory. Remove
it to save memory.

Split man_get_module_manifest() into two functions in preparation for
multi-part relocatable module library support.

libraries.

Rimage generates an image from multiple input modules. However, in
case of building libraries from multiple relocatable ELF files it
doesn't currently construct manifest correctly. It mixes up manifest
provided in TOML with manifest structures in ".module" sections of
modules. Clean this up to only use manifests from ELF and append
configuration from TOML.

Run-time loadable SOF libraries can contain multiple modules. To
prepare to support them add a module context type.

Zephyr logging prints function names, no need to include them

NULL checking should be done before dereferencing, not after. Also
rearrange varoable definition in llext_manager_allocate_module() to
make it more logical.

llext_manager_allocate_module() should return 0 when failing, not an

Loadable libraries can contain multiple modules, where each module
can contain multiple manifest entries, e.g. when providing multiple
Module Adapter drivers. This commit adds support for such libraries,
built by specifying all the modules on rimage command line.

mux.toml doesn't have a demux entry in it, therefore we cannot have
one in .module either, remove it until fixed. Also fix a copy-paste
error in the same code block.

Add a FORCE_ALL_MODULES macro to mtl.toml.h. When this header is then
preprocessed with that macro defined, all module TOML files will be
included. This then can be used to generate module libraries.

Add a parameter to sof_llext_build() to support adding modules to
libraries. Specifying a LIB parameter in that function with a single
value adds that module to a library with that name.
