[Kernel/VFS] Cleanup info query/set+sector size.

Browse Source 
[VFS] Device now exposes name, attributes, component name max length.
[VFS] Fix STFS device to return 0x200 sector size. XCTD compression
      userland code appears to always expect a sector size of 0x200.
[Kernel] Move X_FILE_*_INFORMATION structs to new files.
[Kernel] Move NtQueryInformationFile, NtSetInformationFile,
         NtQueryVolumeInformationFile to new file.
[Kernel] Cleanup implementation of NtQueryInformationFile,
         NetSetInformationFile, NtQueryVolumeInformationFile.
[Kernel] Properly validate arguments to NtQueryInformationFile,
         NetSetInformationFile, NtQueryVolumeInformationFile.
[Kernel] Properly implement query of XFileFsVolumeInformation.
[Kernel] Properly implement query of XFileFsSizeInformation.
[Kernel] Properly implement query of XFileFsAttributeInformation.
