compilers: Reduce sizes of MSVC linked binaries
- For optimization=s add /O1: Use Maximum Optimization (Favor Size),
and remove /Os as it's implied by /O1.
- Because we add /O1, this implies /Gy, i.e. Function-Level Linking, so
unused code can be omitted.
- Add /Gw: Optimize Global Data, so unused data can be omitted.
With buildtype=minsize on x86 this reduces the size of a statically
linked Vala compiler binary from 5 MB down to just 1.87 MB.
