Enable glam asserts in debug builds (#7618)

### What
From <https://docs.rs/glam/latest/glam/#glam-assertions>:

> glam does not enforce validity checks on method parameters at runtime.
For example methods that require normalized vectors as input such as
`Quat::from_axis_angle(axis, angle)` will not check that axis is a valid
normalized vector. To help catch unintended misuse of glam the
debug-glam-assert or glam-assert features can be enabled to add checks
ensure that inputs to are valid.
