This adds the vcpkg triplets and CMake preset to perform release
builds for distribution. These builds are fully static, and currently
intended to be used for the `js` ESVU release.
In the future, linking everything statically into the final binary is
probably not what we will do for released Ladybird builds. Instead, we
may have a "libladybird.so", which is then linked into the binary. But
this should be fine for `js` for now.
