Drop the default buffer size to 8K
The 64k capacity was picked by me a couple of years ago in the initial implementation of buffered IO adaptors: https://github.com/rust-lang/rust/pull/9091/files#diff-b131eeef531ad098b32f49695a031008R62. 64K was picked for symmetry with libuv, which we no longer use. 64K is *way* larger than the default size of any other language that I can find. C, C++, and Java default to 8K, and Go defaults to 4K. There have been a variety of issues filed relating to this such as #31885. Closes #31885
