Don't shrink window log in ZSTD_getCParams()
...
Treat ZSTD_getCParams() and ZSTD_adjustCParams() in the same way
we treat streaming compression. Choose parameters based on the
dictionary size + source size, and assume the source size is small
if unkown. But, don't shrink the window log down in
ZSTD_adjustCParams_internal().

Don't shrink window log when streaming with a dictionary
...
Fixes #2442 .
1. When creating a dictionary keep the same behavior as before.
Assume the source size is 513 bytes when adjusting parameters.
2. When calling ZSTD_getCParams() or ZSTD_adjustCParams() keep
the same behavior as before.
3. When attaching a dictionary keep the same behavior of ignoring
the dictionary size. When streaming this will select the
largest parameters and not adjust them down. But, the CDict
will use the correctly sized parameters, which seems like the
right tradeoff.
4. When not attaching a dictionary (either forced not to, or
using a prefix dictionary) we select parameters based on the
dictionary size + source size, and assume the source size is
small, which is the same behavior as before. But, now we don't
adjust the window log (and hash and chain log) down when the
source size is unknown.
When the source size is unknown all cdicts should attach, except
when the user disables attaching, or `forceWindow` is used. This
means that when streaming with a CDict we end up in the good case
where we get small CDict parameters, and large source parameters.
