Replace lazy_static with once_cell. Fixes #2146.

Motivation

lazy_static!, while a declarative macro, is a macro nonetheless. It can add quite a bit of additional compilation time cost. once_cell::sync::Lazy does the same thing with generics, and can be used more flexibly (i.e. non-static lazily initialized values), and has been proposed to be added to std (see linked issue).

I'm trying to reduce the compile time and dependency tree complexity of a dependent project: bevy, which is using tracing. lazy_static and once_cell are both in our dependency tree and both end up doing the same thing.

Solution

Migrate to once_cell.

This change seems fine to me. I have a very minor preference for making the tracing-core and tracing-subscriber changes in separate branches, but I'm not going to block merging this based on that.

core: prepare to release v0.1.27
18fe1c1 
# 0.1.27 (June 7, 2022)

This release of `tracing-core` introduces a new `DefaultCallsite` type,
which can be used by instrumentation crates rather than implementing
their own callsite types. Using `DefaultCallsite` may offer reduced
overhead from callsite registration.

### Added

- `DefaultCallsite`, a pre-written `Callsite` implementation for use in
  instrumentation crates ([#2083])
- `ValueSet::len` and `Record::len` methods returning the number of
  fields in a `ValueSet` or `Record` ([#2152])

### Changed

- Replaced `lazy_static` dependency with `once_cell` ([#2147])

### Documented

- Added documentation to the `callsite` module ([#2088], [#2149])

Thanks to new contributors @jamesmunns and @james7132 for contributing
to this release!

subscriber: prepare to release v0.3.12
67c7a4c 
# 0.3.12 (Jun 29, 2022)

This release of `tracing-subscriber` adds a new `Layer::event_enabled`
method, which allows `Layer`s to filter events *after* their field
values are recorded; a `Filter` implementation for `reload::Layer`, to
make using `reload` with per-layer filtering more ergonomic, and
additional inherent method downcasting APIs for the `Layered` type. In
addition, it includes dependency updates, and minor fixes for
documentation and feature flagging.

### Added

- **layer**: `Layer::event_enabled` method, which can be implemented to
  filter events based on their field values (#2008)
- **reload**: `Filter` implementation for `reload::Layer` (#2159)
- **layer**: `Layered::downcast_ref` and `Layered::is` inherent methods
  (#2160)

### Changed

- **parking_lot**: Updated dependency on `parking_lot` to 0.13.0
  (#2143)
- Replaced `lazy_static` dependency with `once_cell` (#2147)

### Fixed

- Don't enable `tracing-core` features by default (#2107)
- Several documentation link and typo fixes (#2064, #2068, #2077,
  #2161, #1088)

maybe I'm misunderstanding the release process of this package, but is there a reason that tracing-log#0.2.0, which includes this change, has not been released yet? 🤔
