Detect usage of AMX registers on Windows

[tajila]

#23244 identified that when AMX registers are used on windows additional stack space is needed for the increased size of the XSAVE buffer.

#23472 unconditionally increases the stack size on windows to account for this.

It is possible to detect the usage of AMX at JVM startup time by doing the following:

1. Check CPU support for AMX with __cpuidex
2. Check if the OS supports AMX with _xgetbv
3. Check if AMX is enabled with GetEnabledXStateFeatures

The third check may be a superset of the prior ones.

In order to save stack space we should add this check to conditionally increase the stack size on windows.
