21: Release 0.4.0 r=taiki-e a=taiki-e

Changes:

* [Add support for version-based code generation.](#17) The following conditions are available:

  ```rust
  use const_fn::const_fn;

  // function is `const` on specified version and later compiler (including beta and nightly)
  #[const_fn("1.36")]
  pub const fn version() {
      /* ... */
  }

  // function is `const` on nightly compiler (including dev build)
  #[const_fn(nightly)]
  pub const fn nightly() {
      /* ... */
  }

  // function is `const` if `cfg(...)` is true
  #[const_fn(cfg(...))]
  pub const fn cfg() {
      /* ... */
  }

  // function is `const` if `cfg(feature = "...")` is true
  #[const_fn(feature = "...")]
  pub const fn feature() {
      /* ... */
  }
  ```

* Improve compile time by removing proc-macro related dependencies ([#18](#18), [#20](#20)).
