chore: Simplify tracing with servo_tracing macro (#36661) (#37497)

This pull request refactors existing tracing annotations to leverage the
new `servo_tracing::instrument` macro introduced in #36573.

Specifically, the following transformations were applied:
- Removed `#[cfg_attr(feature = "tracing", ...)]` wrappers.
- Replaced `tracing::instrument` with `servo_tracing::instrument`.
- Removed `level = "trace"`
- Removed `fields(servo_profiling = true)` from tracing attributes
however retained others like `name`. `skip type`

Closes: #36661
