[3/4,v2] meson.bbclass: Allow early compiler tests to be bypassed if necessary

Setting skip_sanity_check=true in the [properties] section of meson.cross allows
early compiler tests to be skipped on cross compilation environments where
sanity applications cant be compiled or tested.

Setting MESON_SKIP_SANITY_CHECK=1 enables this behavior.

This is pretty niche behaviour - is it worth adding to the increasingly complex meson.bbclass?  Can it just be added to the picolibc recipe instead?
