area-System.IO, community-contribution

Milestone: -

According to MS-FSCC, "a value of -1 indicates to the server that it MUST NOT change this attribute for all subsequent operations"
This behavior is incorrect in the scope of .NET, since a call to File.SetLastAccessTime on a open file handle
will cause all future writes to not update the last write tim.

It also triggers STATUS_INVALID_PARAMETER on NFS, since the Windows driver doesn't seem to implement the -1 value (tracking of subsequent write operations)

Fixes dotnet#95096
