runtime: always use LoadLibraryEx to load system libraries
This CL removes a fallback that used LoadLibraryA when the runtime
was loading system DLLs on Windows 7, Windows Server 2008 R2,
or earlier.
We can safely remove that fallback now, as go1.21 will require at least
Windows 8 or Server 2012.
This CL also saves some syscall initialization time and bytes:
new:
init syscall @2.3 ms, 0 ms clock, 1000 bytes, 18 allocs
old:
init syscall @3.6 ms, 0.52 ms clock, 1744 bytes, 24 allocs
Updates #57003
