trop[bot] 2c05608a76 fix: preserve transparency across setResizable toggles on Windows (#51217) ...

After #49428 made `NativeWindowViews::CanResize()` return `resizable_`
for frameless windows (instead of `resizable_ && thick_frame_`),
`HWNDMessageHandler::SizeConstraintsChanged()` started adding
`WS_THICKFRAME` to the window style whenever `CanResize()` reported true.
`WS_THICKFRAME` is incompatible with layered (translucent) windows and
destroys their transparency.

`SetContentSizeConstraints` already guards against this by skipping
`OnSizeConstraintsChanged()` when `!thick_frame_`. `SetResizable` did
not, so toggling resizability on a transparent window (e.g.
`setResizable(false)` then `setResizable(true)`) caused the Chromium
path to add `WS_THICKFRAME` and strip transparency.

Apply the same guard in `SetResizable`. Min/max constraints are still
enforced — Chromium reads them from the widget delegate on every
`WM_GETMINMAXINFO`, independent of `SizeConstraintsChanged()`.
