Fix Check for AAC on Windows N

In the context of Windows N SKU, the isTypeSupported function
does not include support for AAC (Advanced Audio Coding) encoding.
In standard Windows operating systems, AAC encoding relies on the
Media Foundation library. However, this library is not installed
by default in Windows N SKU, resulting in the lack of AAC encoding support.

The straightforward solution is to check whether the system is
running Windows N SKU and return false for AAC support.

An alternative approach involves examining the presence of
the Media Foundation binaries (such as mf.dll). Unfortunately,
this file existence check cannot be performed directly in the
renderer process. The GPU process already handles this check,
but the isTypeSupported API operates synchronously and cannot
utilize a Mojo-based solution.

It’s worth noting that Windows N SKU is optional for European
countries and Korea, although it is not widely used. Therefore,
a simple check based on the product type could be a more effective solution.
