  [PDB] Prevent potential overflow when calculating `Base` in `formatMsfStreamData` (#224662)

The `Base` is calculated as a product of two 32-bits number but the
results is assigned to a 64-bit value. By casting one of the operands to
64-bit, the multiplication is done using the whole width of the `Base`
variable, preventing a potential overflow. This fixes an issue reported
by a CodeQL scan.
