Yong Tang 2c68691b95 Skip UTF-8 BOM bytes from Dockerfile if exists ...

This fix tries to address issues in #23221 where Dockerfile
may consists of UTF-8 BOM. This likely happens when Notepad
tries to save a file as UTF-8 in Windows.

This fix skips the UTF-8 BOM bytes from the beginning of the
Dockerfile if exists.

Additional tests has been added to cover the changes in this
fix.

This fix fixes #23221.
