This is one less host tool we have to compile for every build,
and makes the build tools more portable across host OSes.
The code is also much simpler to maintain.

This reverts commit 37f4178f58.
This change builds gen_idt in the zephyr project tree instead of
building it in outdir of the application. The build process should all
happen inside outdir and no binaries should be placed in the zephyr
tree.

For various reasons its often necessary to generate certain
complex data structures at build-time by separate tools outside
of the C compiler. Data is populated to these tools by way of
special binary sections not intended to be included in the final
binary. We currently do this to generate interrupt tables, forthcoming
work will also use this to generate MMU page tables.
The way we have been doing this is to generatea "kernel_prebuilt.elf",
extract the metadata sections with objcopy, run the tool, and then
re-link the kernel with the extra data *and* use objcopy to pull
out the unwanted sections.
This doesn't scale well if multiple post-build steps are needed.
Now this is much simpler; in any Makefile, a special
GENERATED_KERNEL_OBJECT_FILES variable may be appended to containing
the filenames to the generated object files, which will be generated
by Make in the usual fashion.
Instead of using objcopy to pull out, we now create a linker-pass2.cmd
which additionally defines LINKER_PASS2. The source linker script
can #ifdef around this to use the special /DISCARD/ section target
to not include metadata sections in the final binary.

When calling scripts/gen_idt, if we don't have $ZEPHYR_BASE/scripts in
the path, it will fail, so we can call it with its full path to avoid
such need.

Arch-specific stuff shouldn't be in the toplevel Makefile,
forthcoming patches will soon introduce special interrupt
handling logic for other arches.
