Changkun Ou 0e598e7da4 syscall: add SyscallN
This CL adds a new syscall.SyscallN API.

The proposal discussion also suggests the API should not only for
Windows but other platforms. However, the existing API set already
contain differences between platforms, hence the CL only implements
the Windows platform.

Moreover, although the API offers variadic parameters, the permitted
parameters remains up to a limit, which is selected as 42, and arguably
large enough.

Fixes #46552
