[3.13] gh-140607: Validate returned byte count in RawIOBase.read (GH-140611) (#140730) 
* [3.13] gh-140607: Validate returned byte count in RawIOBase.read (GH-140611)

While `RawIOBase.readinto` should return a count of bytes between 0 and
the length of the given buffer, it is not required to. Add validation
inside RawIOBase.read() that the returned byte count is valid.
(cherry picked from commit 0f0a362768)
