This fix tries to address the issue raised in 26179 where an env file
with non-ascii or utf8 bytes will crash on windows platform.
The issue is two-fold:
- Windows will adds a BOM mark at the begining with Notepad as the editor
- Non-utf8 bytes can not be handled by env file parser.
This fix removes utf8 BOM marker if exists so that utf8 encoded env file
could be processed.
This fix also returns an error (instead of a runtime CreateProcess crash)
if env file contains non-utf8 bytes, thus giving users better experiences.
Additional test cases has been added in unit tests.
This fix fixes 26179.

These validators are only used by runconfig.Parse() or some other part of the
