VS: Map /Fd to ProgramDataBaseFileName for VS 7,8,9 (#14577)

Since commit 42ba1b08 (VS: Separate compiler and linker PDB files,
2013-04-05) the VS generators no longer add ProgramDataBaseFileName.
Therefore we should allow projects to do so by mapping the /Fd option.
For VS >= 10 our flag tables map /Fd to ProgramDataBaseFileName already.
Add the mapping for VS 7, 8, and 9.
