Fix cyclic dep (bevyengine#11523)

# Objective

Rust analyzer kept complaining about a cyclic dependency due to
`bevy_input` having a dev-dependency on `bevy`.

`bevy_input` was also missing `bevy_reflect`'s "smol_str" feature which
it needs to compile on its own.

Fixes bevyengine#10256

## Solution

Remove the dev-dependency on `bevy` from `bevy_input` since it was only
used to reduce imports for 1 test and 3 doc examples by 1 line each, as
`bevy_input` already has dependencies on everything needed for those
tests and doctests to work.

Add `bevy_reflect`'s "smol_str" feature to `bevy_input`'s dependency
list as it needs it to actually compile.
