zstd: Protect against index out-of-bounds when decoding sequences
Previously, index out-of-bounds could occur when copying match_length bytes while decoding whatever sequence happened to overflow `dest`. Now, each sequence checks that there is enough room for the full sequence_length (literal_length + match_length) before doing any copying.
Fixes the failing inputs found here: https://github.com/ziglang/zig/issues/24817#issuecomment-3192927715
