[FIXED JENKINS-25511] [JENKINS-17309] Reverted XML escaping of message.

Revert of fix for JENKINS-17309. Previous solution was too aggressive, it makes sense to escape only messages from parsers that parse non-XML files. XML parsers should not escape entities at all.
AbstractAnnotation never escapes entities now, only GCC parser escapes and invokes constructor with escaped message.
