[lldb][Format] Fall back to old function.name-with-args if language frame format is emtpy (#148235)
There is currently no way to prevent `${function.name-with-args}` from
using the `plugin.cplusplus.display.function-name-format` setting. Even
if the setting is set to an empty string. As a way to disable formatting
by language plugin, this patch makes it so
`plugin.cplusplus.display.function-name-format` falls back to the old
way of printing `${function.name-with-args}`. Even if we didn't want to
add a fallback, making the setting an empty string shouldn't really
"succeed".
