Kconfig LTO: Prevent with native simulator based targets 

LTO cannot be really used with the native simulator based
targets neither today.

When doing a partial link as we do for these targets
the linker will complain if we are mixing LTO and non LTO
built code, and fall back to only produce non-LTO output.
(The link warning will cause twister to fail the test)

Today not all inputs to this partial link are built
with LTO enabled (offsets.c and the app library are not).

Even if they were, the native targets are mostly
a test and debugging facility, so optimizations like
these are not beneficial in general.

Let's just prevent selecting LTO for these targets.
