Define __KERNEL__ macro during compilation and place the module in separate library
Remove default library linking to m or libc on NuttX. Add these in platform layer instead, since
they are different on kernel and user side

There was an error that PX4_CRYPTO was cached accross variants, if it was
defined just for one variant.
This synchronizes the caching of BOARD_CRYPTO with other similar BOARD_ flags;
it is set as INTERNAL and "1" when enabled.
Also remove handling of BOARD_KEYSTORE; it is not used anywhere after
changing the crypto under src/drivers. If a separate keystore driver
is required, it is just selected as any other driver in px4board

- cmake NuttX build wrapper compile in place instead of copying source tree to build directory
- slightly faster skipping necessary copying (depending on system)
- allows debugging in place
- easier to work directly in NuttX following official documentation
- simplifies overall build which should make it easier to resolve any remaining NuttX dependency issues in the build system
- the downside is switching back and forth between different builds always require rebuilding NuttX, but I think this is worth the improved developer experience
- also no longer builds px4io and bootloader in every single build, for most users these rarely change and we're wasting a lot of build time
