Merge bitcoin/bitcoin#19690: util: improve FindByte() performance 
72efc26439 util: improve streams.h:FindByte() performance (Larry Ruane)
604df63f6c [bench] add streams findbyte (gzhao408)

Pull request description:

  This PR is strictly a performance improvement; there is no functional change. The `CBufferedFile::FindByte()` method searches for the next occurrence of the given byte in the file. Currently, this is done by explicitly inspecting each byte in turn. This PR takes advantage of `std::find()` to do the same more efficiently, improving its CPU runtime by a factor of about 25 in typical use.
