arm32: fold UNWIND(.fnstart/.fnend) into the FUNC macros

This change applies to arm32 assembler sources.

Instead of using UNWIND(.fnstart) after FUNC or LOCAL_FUNC and
UNWIND(.fnend) before END_FUNC, let's fold these statements into the
FUNC macros.

The .fnstart/.fnend directives mark the start and end of a function
with an unwind table entry (.ARM.exidx) and therefore a function
without them has no entry and cannot be unwound. This means that a
stack dump (on abort or panic) would stop when reaching such a
function.

As a result of this patch, a small number of functions now have an
entry in the unwind table when they had none before (the functions
which were using FUNC or LOCAL_FUNC but had no .fnstart/.fnend). It was
almost always a bug and this pacth only increases the size of the
.ARM.exidx section by a few bytes (tested on QEMU).

arm32: move the UNWIND() macro to <asm.S>

All the users of the UNWIND() macro include <asm.S> already, which is
therefore a good place to define this macro. Let's move it from
<kernel/unwind.h> to <asm.S>, remove a couple of duplicates in
assembler files, and drop the useless includes.
