Remove QuicSleep from platform.

This has a default implementation, with no internal override, and no override in
Envoy.  Chromium has an unused implementation at
net/quic/platform/impl/quic_sleep_impl.h but because of the way QUICHE overrides
work this is not actually effective.  (Overrides need to be placed in
net/third_party/quiche/overrides/quiche_platform_impl/ in order to take
precedent over the default implementation packaged with QUICHE.)

I verified that absl/time/time.h and absl/time/clock.h are included at [1] and
absl/time exists at [2].  Also, we know that they work in Chromium since it
already uses the default implementation, which relies on these includes.

QUICHE

QUICHE stands for QUIC, Http/2, Etc. It is Google‘s production-ready implementation of QUIC, HTTP/2, HTTP/3, and related protocols and tools. It powers Google’s servers, Chromium, Envoy, and other projects. It is actively developed and maintained.

There are two public QUICHE repositories. Either one may be used by embedders, as they are automatically kept in sync:

To embed QUICHE in your project, platform APIs need to be implemented and build files need to be created. Note that it is on the QUICHE team's roadmap to include default implementation for all platform APIs and to open-source build files. In the meanwhile, take a look at open source embedders like Chromium and Envoy to get started:

To contribute to QUICHE, follow instructions at CONTRIBUTING.md.

QUICHE is only supported on little-endian platforms.
