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. Signed-off-by: Joakim Andersson <joakim.andersson@nordicsemi.no>
