Improve compilation error on 32-bit (#2424)

Browse Source 
## Issue Addressed

Closes #1661

## Proposed Changes

Add a dummy package called `target_check` which gets compiled early in the build and fails if the target is 32-bit

## Additional Info

You can test the efficacy of this check with:

```
cross build --release --manifest-path lighthouse/Cargo.toml --target i686-unknown-linux-gnu
```

In which case this compilation error is shown:

```
error: Lighthouse requires a 64-bit CPU and operating system
  --> common/target_check/src/lib.rs:8:1
   |
8  | / assert_cfg!(
9  | |     target_pointer_width = "64",
10 | |     "Lighthouse requires a 64-bit CPU and operating system",
11 | | );
   | |__^
