Kbuild: add Rust support

Browse Source 
Having most of the new files in place, we now enable Rust support
in the build system, including `Kconfig` entries related to Rust,
the Rust configuration printer and a few other bits.

config RUST_DEBUG_ASSERTIONS
bool "Debug assertions"

help
Enables rustc's `-Cdebug-assertions` codegen option.
This flag lets you turn `cfg(debug_assertions)` conditional
compilation on or off. This can be used to enable extra debugging
code in development but not in production. For example, it controls
the behavior of the standard library's `debug_assert!` macro.
Note that this will apply to all Rust code, including `core`.
If unsure, say N.
config RUST_OVERFLOW_CHECKS
bool "Overflow checks"

depends on RUST
help
Enables rustc's `-Coverflow-checks` codegen option.
This flag allows you to control the behavior of runtime integer
overflow. When overflow-checks are enabled, a Rust panic will occur
on overflow.
Note that this will apply to all Rust code, including `core`.
If unsure, say Y.
