kasan: default to inline instrumentation
KASan inline instrumentation can yield up to a 2x performance gain at the
cost of a larger binary.
Make inline instrumentation the default, as suggested in the bug report
below.
When an architecture does not support inline instrumentation, it should
set ARCH_DISABLE_KASAN_INLINE, as done by PowerPC, for instance.
