The goal of `bevy_platform_support` is to provide a set of platform agnostic APIs, alongside platform-specific functionality. This is a high traffic crate (providing things like HashMap and Instant). Especially in light of https://github.com/bevyengine/bevy/discussions/18799, it deserves a friendlier / shorter name. Given that it hasn't had a full release yet, getting this change in before Bevy 0.16 makes sense. - Rename `bevy_platform_support` to `bevy_platform`.
