[Zion] Use a slab allocator for 64 byte and 128 byte allocs.
...
This has no effect on page usage for now (each uses a small amount of
pages so has some overhead.
However it does reduce the active allocations from
234 -> 146 (64B)
61 -> 51 (128B)

[Zion] Free memory that was allocated with the slab allocator.
...
This reduces the number of active allocs by ~ 200.
Size 8: 142 -> 2
Size 16: 319 > 313
Size 32: 364-> 312

[Zion] Add more debug information about kernel heap usage.
...
This will be helpful as we work to improve it.
Without deallocations, we currently stand at the following alloc numbers
8 - 142
16 - 319
32 - 364
unsized - 305
total page usage including slabs is 12.

[Zion] Make kernel slab allocation failures less chatty.
...
We started to hit this constraint but the allocators are due for
a redesign that actually does deallocation soon.

Add a basic kernel heap object.

Currently allocation always fails because we don't
have a way to allocate a physical page.
