[Windows][AArch64] Use base introspection table implementation

[amitin]

This pull request includes 3 fixes:

1. Using explicit 64-bit integer type to hold HW capabilities flags. Previously it was 'unsigned long' which is 32-bit on Windows and can't hold all the flags we've got for AArch64.
2. Provided a fix for a problem with MSVC default compiler which can't compile array initializer code with a typecast in it (which is not really necessary, but I provided a conditionally compiled code to keep the existing behaviour for other compilers).
3. After all of the fixes applied the base introspection table implementation for AArch64 finally works for Windows.
