CHANGE: Added isEnabledByDefault constructor option to generated action sets.

[Walter-Hulsebos]

Description

Changed code generation of actions sets so they now have an optional isEnabledByDefault parameter and check in it's constructor. It will then automatically call .Enable() at the end of the constructor if set to true.

It's handy to have to ability to enable and disable all InputActionMaps. But there should be an option to have it enabled by default - for when you don't need the control and want to minimize code bloat.

Changes made

Please write down a short description of what changes were made.

• Added optional isEnabledByDefault parameter to generated action set's C# class.
• Added call to .Enable() at end of generated constructor when isEnabledByDefault is true.
• Re-generated existing actions sets to implement the new functionality.

Notes

• This requires no change to existing API apart from re-generating existing action sets. The constructor is functionally the same and sending the parameter is purely optional and defaults to false.

• When using (isEnabledByDefault: true) it means you're restricted to where/when you're creating the action set; for instance you can't create it in Reset() anymore because it'll call .Enable() at a time it can't/shouldn't.
