Merge pull request #24329 from ziglang/writergate

Deprecates all existing std.io readers and writers in favor of the newly
provided std.io.Reader and std.io.Writer which are non-generic and have the
buffer above the vtable - in other words the buffer is in the interface, not
the implementation. This means that although Reader and Writer are no longer
generic, they are still transparent to optimization; all of the interface
functions have a concrete hot path operating on the buffer, and only make
vtable calls when the buffer is full.
