Remove everything except Instant from bevy_utils::time (#17158)
# Objective

- Contributes to #11478
- Contributes to #16877

## Solution

- Removed everything except `Instant` from `bevy_utils::time`

## Testing

- CI

---

## Migration Guide

If you relied on any of the following from `bevy_utils::time`:

- `Duration`
- `TryFromFloatSecsError`

Import these directly from `core::time` regardless of platform target
(WASM, mobile, etc.)

If you relied on any of the following from `bevy_utils::time`:

- `SystemTime`
- `SystemTimeError`

Instead import these directly from either `std::time` or `web_time` as
appropriate for your target platform.

## Notes

`Duration` and `TryFromFloatSecsError` are both re-exports from
`core::time` regardless of whether they are used from `web_time` or
`std::time`, so there is no value gained from re-exporting them from
`bevy_utils::time` as well. As for `SystemTime` and `SystemTimeError`,
no Bevy internal crates or examples rely on these types. Since Bevy
doesn't have a `Time<Wall>` resource for interacting with wall-time (and
likely shouldn't need one), I think removing these from `bevy_utils`
entirely and waiting for a use-case to justify inclusion is a reasonable
path forward.

Stress tests

These examples are used to stress test Bevy's performance in various ways. These should be run with the "stress-test" profile to accurately represent performance in production, otherwise they will run in cargo's default "dev" profile which is very slow.

Example Command

cargo run --profile stress-test --example <EXAMPLE>
