Wenzhao Liao da991304c9 rust: module_param: support bool parameters
Add support for parsing boolean module parameters in the Rust
module! macro.

Currently, only integer types are supported by the `module_param!`
macros. This patch implements the `ModuleParam` trait for `bool`
by delegating the string parsing to the existing C implementation
via `kstrtobool_bytes()`. It also wires up `PARAM_OPS_BOOL` so that
the Rust parameter system correctly links to the C `param_ops_bool`
structure.

For demonstration and verification, a boolean parameter is added
to `samples/rust/rust_minimal.rs`.

Support for boolean parameters will initially be used by the Rust
null block driver [1].
