Joe Tsai 0d8a4bfc96 bufio: add Writer.AvailableBuffer 
This adds a new Writer.AvailableBuffer method that returns
an empty buffer with a possibly non-empty capacity for use
with append-like APIs.

The typical usage pattern is something like:
	b := bw.AvailableBuffer()
	b = appendValue(b, v)
	bw.Write(b)

It allows logic combining append-like APIs with bufio.Writer to avoid
needing to allocate and manage buffers themselves and allows the
append-like APIs to directly write into the buffer for a bufio.Writer.

Fixes #47527
