Revert of Update Zlib to version 1.2.8 (patchset #10 id:220001 of https://codereview.chromium.org/1955383002/ )

Reason for revert:
Broke the Windows Debug GPU FYI builder:

https://build.chromium.org/p/chromium.gpu.fyi/builders/GPU%20Win%20Builder%20%28dbg%29/builds/41421

fx_zlib.gzlib.obj : error LNK2005: _gzopen_w already defined in zlib.gzlib.obj

initial\chrome.dll : fatal error LNK1169: one or more multiply defined symbols found

Possibly because they use shared components with a GYP build.

Original issue's description:
> Update Zlib to version 1.2.8
>
> merge the latest open source zlib into chromium external projects
>
>  Version 1.2.8 fixes a very rare bug in decompression. All users are encouraged to upgrade immediately. Version 1.2.8 also has these improvements:
>     - Add new inflateGetDictionary() function
>     - Fix bug where gzopen() immediately followed by gzclose() would write an empty file instead of an empty gzip stream.
>     - Fix bug in gzclose() when gzwrite() runs out of memory
>     Version 1.2.7 has many portability improvements over 1.2.6, and has these enhancements:
>     - Fix bug in gzclose_w() when gzwrite() fails to allocate memory
>     - Add "x" (O_EXCL) and "e" (O_CLOEXEC) modes support to gzopen()
>     - Add gzopen_w() in Windows for wide character path names
>     - Fix type mismatch between get_crc_table() and crc_table
>     Version 1.2.6 has many changes over 1.2.5, including these improvements:
>     - gzread() can now read a file that is being written concurrently
>     - gzgetc() is now a macro for increased speed
>     - Added a 'T' option to gzopen() for transparent writing (no compression)
>     - Added deflatePending() to return the amount of pending output
>     - Allow deflateSetDictionary() and inflateSetDictionary() at any time in raw mode
>     - deflatePrime() can now insert bits in the middle of the stream
>     - ./configure now creates a configure.log file with all of the results
>     - Added a ./configure --solo option to compile zlib with no dependency on any libraries
>     - Fixed a problem with large file support macros
>     - Fixed a bug in contrib/puff
>     - Many portability improvements
