windows: add NtSetInformationFile
Added NtSetInformationFile and some const values related to it.
The doc for the function and the values of the file information class
can be found here:
https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/nf-ntifs-ntsetinformationfile
The values of the flags in the individual FILE_INFORMATION_CLASS can be
found here:
FILE_RENAME_INFORMATION - https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/ns-ntifs-_file_rename_information
FILE_DISPOSITION_INFORMATION_EX - https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/ntddk/ns-ntddk-_file_disposition_information_ex
FILE_CASE_SENSITIVE_INFORMATION - https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/ns-ntifs-_file_case_sensitive_information
FILE_LINK_INFORMATION - https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/ns-ntifs-_file_link_information
The other file information classes do not have flag values.
Fixes golang/go#48933
