Kernel: Enable LTO for kernel_heap if `ENABLE_KERNEL_LTO` is set
By enabling LTO for the kernel_heap object too, we open the door for
optimization opportunities that come from (partially) inlining `::new`
or kmalloc. Every software spends a non-trivial amount of its run time
on allocating memory, so hopefully this change will make LTO builds even
faster.
