394: Detect if the rt flag is defined in the PAC/HAL r=AfoHT a=korken89

This stops RTIC applications from compiling if one has forgotten to set the `rt` flag in the PAC/HAL.

The error:

```
error[E0433]: failed to resolve: could not find `interrupt` in `you_must_enable_the_rt_feature_for_the_pac_in_your_cargo_toml`
 --> src/main.rs:8:1

  | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ could not find `interrupt` in `you_must_enable_the_rt_feature_for_the_pac_in_your_cargo_toml`
  |
  = note: this error originates in an attribute macro (in Nightly builds, run with -Z macro-backtrace for more info)
```
