Handle VK_SUBOPTIMAL_KHR as a valid error code to fix Android performance.

Fixes #88355.

This should basically revert the behavior of presentation handling to the behavior previous to #87340.

Copied from my comment in the code.

// Godot does not currently support native rotation in Android when creating the swap chain. It intentionally uses
// VK_SURFACE_TRANSFORM_IDENTITY_BIT_KHR instead of the current transform bits available in the surface capabilities.
// Choosing the transform that leads to optimal presentation leads to distortion that makes the application unusable,
// as the rotation of all the content is not handled at the moment.
//
// VK_SUBOPTIMAL_KHR is accepted as a successful case even if it's not the most efficient solution to work around this
// problem. This behavior should not be changed unless the swap chain recreation uses the current transform bits, as
// it'll lead to very low performance in Android by entering an endless loop where it'll always resize the swap chain
// every frame.

I've verified this fixes the issue in Android for me at least. The easiest way to spot the error was that the frame time stats were completely wrong as the swap chain was constantly getting trashed.
