Enhance testing: Skip fused_optimizer tests if not supported.

Added condition check to skip fused_optimizer tests if FusedAdam and FusedLamb are not supported by the accelerator. This enhancement ensures that the tests are appropriately skipped when the hardware configuration does not support these optimizers, preventing potential issues.

Details:

• Introduced a condition check to determine support for FusedAdam and FusedLamb.
• If not supported, fused_optimizer tests are skipped to improve test reliability.
• Improved compatibility and stability across different hardware configurations.
