[syscalls] Change vmar_... calls

- Create zx_vm_option_t type
- Change ZX_VM_FLAG_... to ZX_VM_... and make them new type.
- Change int32_t flags parameters to zx_vm_option_t options
- Make the options parameter be second.

- Modify vmar_..._old functions to keep other repos working.
Once they've all been updated these functions will go away.

[test][vmo] switch the benchmarking code to using zx_ticks_get

This causes it to not enter the kernel so much and cleans up a ktrace of
the bench.

[kernel][vmo] Optimize page address lookup and commit

For the case of non-cloned paged VMOs, this speeds up Lookup on a 32MB
VMO from ~1.2ms to ~700us.

Originally landed in 3d79df1b2030537337fadc3bb95e32d6dfec4add, but
reverted due to bugs. This diff fixes the bugs and adds tests.
