  1. llext: automatically select LLEXT type 

    When using a clang Cadence toolchain to build SOF and LLEXT modules
we need to select a different LLEXT type than when using a Zephyr gcc
toolchain.

  2. llext: remove hard-coded section names 

    It was clear that hard-coded section names aren't reliable enough but
they broke down way earlier than has been expected.

This patch replaces hard-coded sections with a loop, scanning all
sections and selecting them based on their flags and types.

  3. llext: check a Kconfig option to select ld flags 

    When using xt-clang we cannot build shared objects, so we use '-r' to
link relocatable objects. But the decision shouldn't be made based on
the name of the compiler, but based on the selected LLEXT_BINARY_TYPE
option.
