KVM: selftests: kvm_vm_elf_load() and elfhdr_get() should close fd

kvm_vm_elf_load() and elfhdr_get() open one file each, but they
never close the opened file descriptor. If a test repeatedly
creates and destroys a VM with __vm_create(), which
(directly or indirectly) calls those two functions, the test
might end up getting a open failure with EMFILE.
Fix those two functions to close the file descriptor.

KVM: selftests: Use the right memslot for code, page-tables, and data allocations

Now that kvm_vm allows specifying different memslots for code, page tables,
and data, use the appropriate memslot when making allocations in
common/libraty code. Change them accordingly:

- code (allocated by lib/elf) use the CODE memslot
- stacks, exception tables, and other core data pages (like the TSS in x86)
use the DATA memslot
- page tables and the PGD use the PT memslot
- test data (anything allocated with vm_vaddr_alloc()) uses the TEST_DATA
memslot

No functional change intended. All allocators keep using memslot #0.

KVM: selftests: Get rid of kvm_util_internal.h

Fold kvm_util_internal.h into kvm_util_base.h, i.e. make all KVM utility
stuff "public". Hiding struct implementations from tests has been a
massive failure, as it has led to pointless and poorly named wrappers,
unnecessarily opaque code, etc...

Not to mention that the approach was a complete failure as evidenced by
the non-zero number of tests that were including kvm_util_internal.h.

KVM: selftests: Expose align() helpers to tests

Refactor align() to work with non-pointers and split into separate
helpers for aligning up vs. down. Add align_ptr_up() for use with
pointers. Expose all helpers so that they can be used by tests and/or
other utilities. The align_down() helper in particular will be used to
ensure gpa alignment for hugepages.

No functional change intended.

[Added sepearate up/down helpers and replaced open-coded alignment
bit math throughout the KVM selftests.]

KVM: selftests: Unconditionally use memslot 0 for vaddr allocations

Drop the memslot param(s) from vm_vaddr_alloc() now that all callers
directly specific '0' as the memslot. Drop the memslot param from
virt_pgd_alloc() as well since vm_vaddr_alloc() is its only user.
I.e. shove the hardcoded '0' down to the vm_phy_pages_alloc() calls.

No functional change intended.
