Re-export smallvec crate from bevy_utils (#11006)

Matches versioning & features from other Cargo.toml files in the
project.

# Objective
Resolves #10932 

## Solution
Added smallvec to the bevy_utils cargo.toml and added a line to
re-export the crate. Target version and features set to match what's
used in the other bevy crates.
