Separate define for 32/64 ZSTD_WINDOWLOG_MAX

[GregSlazinski]

Is it possible to replace the following:

define ZSTD_WINDOWLOG_MAX ((U32)(MEM_32bits() ? 25 : 27))

to:

define ZSTD_WINDOWLOG_MAX_32 25

define ZSTD_WINDOWLOG_MAX_64 27

define ZSTD_WINDOWLOG_MAX ((U32)(MEM_32bits() ? ZSTD_WINDOWLOG_MAX_32 : ZSTD_WINDOWLOG_MAX_64))

I'm targetting both 32/64 platforms, and I want to know the minimum supported value by both platforms, in my case I will always use ZSTD_WINDOWLOG_MAX_32

LZHAM library does the same approach.

Thanks to this I don't need to store the WindowLog size in the compressed stream, but I can always calculate it based on decompressed size (which I already know).
