This commit fixes a request handling bug introduced in #6868, which
caused OPA to treat all incoming chunked requests as if they had
zero-length request bodies.
The fix detects cases where the request body size is unknown in the
DecodingLimits handler, and propagates a request context key down to
the `util.ReadMaybeCompressedBody` function, allowing it to correctly
select between using the original `io.ReadAll` style for chunked
requests, or the newer preallocated buffers approach (for requests of
known size).
This change has a small, but barely visible performance impact for large
requests (<5% increase in GC pauses for a 1GB request JSON blob), and
minimal, if any, effect on RPS under load.
Fixes: #6904
