wails `window.ToggleFrameless() api`

Implements the window.ToggleFrameless() api internally it just uses the window.setFrameless toggling it as the opposite of the current value so Developer does not need to card about the current state to swap it

Changes:

Runtime will need to be updated on dev machines as I reorganized the message processor values to keep the ToggleXXX in the same range
Regenerated new events
Updated messageprocessor_window.go
Updated runtime window.ts
Updated API example in `v3/examples/

Walkthrough

A new ToggleFrameless() API method has been introduced, allowing windows to toggle between frameless and normal states. This addition required updates across the runtime, event types, changelog, and example assets. Associated event IDs, constants, and exported interfaces were updated, and a new event type and handler were added to support this feature.

Poem

A rabbit hopped up to the screen,
Saw windows shift from seen to unseen—
With frameless toggles, click and gleam,
The borders vanish, so pristine!
Code and carrots, side by side,
In alpha sixty-eight we ride.
