lib: Add limits.h

We already include limits.h from a couple places (libfdt and the
sbi test for riscv). We should provide our own limits.h rather than
depend on the build environment as some cross environments may not
support it (building riscv with a ilp32d toolchain fails, for
example).

We guard each definition to ensure we only provide them when the
sizes match our expectations. If something is strange then the
define won't be created, and either the includer won't notice since
it wasn't used or the build will break and limits.h can be extended.
