Implement WEBP_DSP_INIT with SRWLOCK for Windows

A slim reader/writer (SRW) lock can be initialized statically with the
constant SRWLOCK_INIT. It is the only Windows synchronization object I
can find with this property.

Note: On old Windows versions that don't have SRWLOCK, use the fallback,
thread-unsafe implementation.

Change a NOLINT comment to a NOLINTNEXTLINE comment to prevent
clang-format from aligning the #else and #endif comments in undesired
way.

WebP codec is a library to encode and decode images in WebP format. This package contains the library that can be used in other programs to add WebP support, as well as the command line tools ‘cwebp’ and ‘dwebp’ to compress and decompress images respectively.

See https://developers.google.com/speed/webp for details on the image format.

The latest source tree is available at https://chromium.googlesource.com/webm/libwebp

It is released under the same license as the WebM project. See https://www.webmproject.org/license/software/ or the “COPYING” file for details. An additional intellectual property rights grant can be found in the file PATENTS.
