  [compiler-rt] [windows] Add more assembly patterns for interception

To intercept the functions in Win11's ntdll.dll, we need to use the trampoline
technique because there are bytes other than 0x90 or 0xcc in the gaps between
exported functions.  This patch adds more patterns that appear in ntdll's
functions.
