os.isCygwinPty: Fix a bug, replace kernel32 call, and optimize
- Fixes the first few code units of the name being omitted (it was using `@sizeOf(FILE_NAME_INFO)` as the start of the name bytes, but that includes the length of the dummy [1]u16 field and padding; instead the start should be the offset of the dummy [1]u16 field)
- Replaces kernel32.GetFileInformationByHandleEx call with ntdll.NtQueryInformationFile
+ Contributes towards #1840
- Checks that the handle is a named pipe first before querying and checking the name, which is a much faster call than NtQueryInformationFile (this was about a 10x speedup in my probably-not-so-good/take-it-with-a-grain-of-salt benchmarking)
