Add a new config option to allow to select the default compile
optimization level for the kernel.
Select the optimization for size by default if the small_flash feature is
set. Otherwise "Optimize for performance" is set.
Add the small_flash feature flag to all (sub)targets which had the
optimization for size in their default kernel config.
Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new
setting.
Exceptions to the above are:
- lantiq, where the optimization for size is only required for the
xway_legacy subtarget but was set for the whole target
- mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have
plenty of space and an optimization for size doesn't make much sense
- rb532, which has 128MByte flash

THIN_ARCHIVES option is enabled by default in the kernel configuration
and no one target config disables it. So enable it by default and remove
this symbol from target specific configs to keep them light.

New FUTEX_PI configuration symbol enabled if FUTEX and RT_MUTEX symbols
are enabled. Both of these symbols are enabled by default in the
generic config, so enable FUTEX_PI by default too to keep platform
specific configs minimal.

OVERLAY_FS config symbol selects EXPORTFS since 4.12 kernel, we have
OVERLAY_FS enabled by default, so enable EXPORTFS in the generic config
of 4.14 and remove this option from platform specific configs.

DRM_LIB_RANDOM config symbol selected only by DRM_DEBUG_MM_SELFTEST
which is disable by default, so disable DRM_LIB_RANDOM by default too.

These options do not used by any supported arch, so disable them by
default to make arch configs a bit more clean.

Only one arch (x86_64) enables this option. So disable
ARCH_WANTS_THP_SWAP by default and remove referencies to it from all
configs (except x86_64) to make them clean.
