Discard the eh_frame section when C++ exceptions are disabled.

In principle the eh_frame may be used for other purposes such as
backtracing when linking C programs, then Zephyr compiles each source
file with '-fno-asynchronous-unwind-tables', thus keeping the eh_frame
in the elf output just takes up space.

When using gcc/ld, then the eh_frame is generally generally discarded
per default, however for clang/lld it will be included but give a
warning that the section is auto-placed.

Some platforms already discards the eh_frame, so unify this for all
targets.

As eh_frame is now discarded in linker scripts then post processing step
of removing the section during hex or bin conversion can also be
removed.
