assert: Add option to disable condition from assertion message

Browse source 
Add Kconfig option to disable the conditional expression in the assert
that failed. This would save code space, and file and line provides
better information than the conditional expression in case where
the same expression would be asserted upon.

For example __ASSERT_NO_MSG(buf) wouldn't make much sense in
configuration where CONFIG_ASSERT_NO_FILE_INFO was enabled.
