qmuntal 176a2154aa cmd/link: use >4GB base address for 64-bit PE binaries ...

Windows prefers 64-bit binaries to be loaded at an address above 4GB.

Having a preferred base address below this boundary triggers a
compatibility mode in Address Space Layout Randomization (ASLR) on
recent versions of Windows that reduces the number of locations to which
ASLR may relocate the binary.

The Go internal linker was using a smaller base address due to an issue
with how dynamic cgo symbols were relocated, which has been fixed in
this CL.

Fixes #73561.
