We should convert ERROR_PRIVILEGE_NOT_HELD to AccessDeniedException

[iseki zero]

Hello maintainers,

When we access a file that requires UAC upgrade on Windows, we will get 
error code ERROR_PRIVILEGE_NOT_HELD. But the 
src/java.base/windows/classes/sun/nio/fs/WindowsException.java haven't 
convert the error code to AccessDeniedException.

In 2 years ago I opened a PR on github 
https://github.com/openjdk/jdk/pull/15221, should I continue work for it?

Thank you.
