We use const helpers in form of
const size_t RUST_CONST_HELPER_ARCH_SLAB_MINALIGN = ARCH_SLAB_MINALIGN;
to aid generation of constants by bindgen because it is otherwise a
macro definition of an expression and bindgen doesn't expand the
constant. The helpers are then have `RUST_CONST_HELPER` prefix stripped
and exposed to Rust code as if `ARCH_SLAB_MISALIGN` is generated
natively by bindgen.
This works well for most constants, but on RISC-V, `ARCH_SLAB_MINALIGN`
is defined directly as literal constant if `!CONFIG_MMU`, and bindgen
would generate `ARCH_SLAB_MINALIGN` directly, thus conflict with the
one generated through the helper.
To fix this, we simply need to block bindgen from generating directly
without going through helper.

If SMP is disabled, arch_spinlock_t is defined as a ZST which triggers a Rust

These functions use the __preserve_most calling convention, which neither bindgen
nor Rust currently understand, and which Clang currently declares to be unstable.

These constants are sometimes not recognized by bindgen depending on config.
We use const helpers to aid bindgen, to avoid conflicts when constants are
recognized, block generation of the non-helper constants.
