rS351108: Move phys_avail definition into MI code. It is consumed in the MI layer and

Summary

I need to move phys_avail and dump_avail into MI code so that I can write boot time allocators. This also eliminates a lot of confusing redundant code and definitions. Since MI is manipulating these arrays it makes sense to define them MI.

The following two revisions depend on this refactoring:

Test Plan

I have built universe and tested on amd64.

sys/vm/vm_param.h
132	Maybe `(PHYS_AVAIL_ENTRIES + 2)` (similar to how the default for PHYS_AVAIL_ENTRIES is defined above)
sys/vm/vm_phys.c
122	Do you want to add a note here to say something like: "Initially dump_avail matches phys_avail, but phys_avail is modified during boot to provide early memory allocations before the VM system is able to allocate memory."?

sys/mips/mips/machdep.c
144	I think this can actually be PHYS_AVAIL_ENTRIES, but it doesn't really matter.
