adbe2cb17e cmake,cosmetics: apply cmake-format
using the defaults present in 0.6.13 and setting
--first-comment-is-literal to avoid reflowing the copyright block and
--max-subgroups-hwrap 3 (default is 2) to avoid making some short set()
statements multi-line.

Style notice: Write unique, descriptive link text that makes sense
without the surrounding text. Don't use phrases such as this document,
this article, or click here.

8151f388eb move VP8GetCPUInfo declaration to cpu.c
This avoids defining a version in each translation unit when using
__declspec(dllexport) which causes failures due to multiply defined
symbols with clang-cl:

118e0035df deps.cmake: remove unneeded header checks
These were picked up when matching autoconf's default checks and aren't
useful except to compare the generated config.h. Removing them speeds up
cmake, especially on windows where creating new processes is slow.

Code" as the added indirection to 'code-length-code' and the undefined
'encoded-code-lengths' doesn't add much.
