Michał Chojnowski 185a032044 utils/stream_compressor: allocate memory for zstd compressors externally 
The default and recommended way to use zstd compressors is to let
zstd allocate and free memory for compressors on its own.

That's what we did for zstd compressors used in RPC compression.
But it turns out that it generates allocation patterns we dislike.

We expected zstd not to generate allocations after the context object
is initialized, but it turns out that it tries to downsize the context
sometimes (by reallocation). We don't want that because the allocations
generated by zstd are large (1 MiB with the parameters we use),
so repeating them periodically stresses the reclaimer.

We can avoid this by using the "static context" API of zstd,
in which the memory for context is allocated manually by the user
of the library. In this mode, zstd doesn't allocate anything
on its own.

The implementation details of this patch adds a consideration for
forward compatibility: later versions of Scylla can't use a
window size greater than the one we hardcoded in this patch
when talking to the old version of the decompressor.

(This is not a problem, since those compressors are only used
for RPC compression at the moment, where cross-version communication
can be prevented by bumping COMPRESSOR_NAME. But it's something
that the developer who changes the window size must _remember_ to do).

Fixes #24160
Fixes #24183
