property: Add support for const (read-only) values

There is already support for setting a property as const
(see vtable.hpp and corresponding test cases).
Implement this in the generated code by adding support
for a new yaml flag.

Closes openbmc/openbmc#2028

Tested: Added the const flag to the Software Priority property,
and changing the value via REST and busctl would fail with
"org.freedesktop.DBus.Error.PropertyReadOnly", but the code
update app was able to set its value.
