const VDso * Create (const HandoffEnd::Elf &elf_image,ktl::span<KernelHandle<VmObjectDispatcher>, userboot::kNumVdsoVariants>vmo_kernel_handles,KernelHandle<VmObjectDispatcher> *time_values_handle)
This is called only once, at boot time.
The created VDso will retain RefPtrs to the created VmObjectDispatchers,
but ownership of the wrapping handles are given to the caller.
The RoDso VMO is created in vmo_kernel_handles[Variant::NEXT]
with the VDso variants in the other slots.

uintptr_t base_address (const fbl::RefPtr<VmMapping> & code_mapping)Given VmAspace::vdso_code_mapping_, return the vDSO base address.

void SetMonotonicTicksOffset (zx_ticks_t new_offset)Sets the monotonic ticks offset in all of the vDSO variants' TimeValues structure. This will
be called on system resume to update the amount of time the system spent in a suspended state.
