remove `transient` keyword in favour of `transient` parameter

[zaucy]

-transient MyTransient;
+component MyTransient(transient);

This will remove a bunch of ecsact_runtime functions that are just duplicates and instead we can have a check if a component is a transient instead.

transient will be a boolean so these are all valid and the same

component MyTransient(transient);
component MyTransient(transient: true);

You can be explicit and mark something as non-transient as well if you'd like

component MyComponent(transient: false);
