[PATCH v3 22/23] xen/Kconfig: introduce HAS_STATIC_MEMORY

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

Architectures that implement guest_physmap_add_pages() select
HAS_STATIC_MEMORY; STATIC_MEMORY then depends on it.  ARM selects the
new flag; RISC-V does not, so CONFIG_STATIC_MEMORY is unavailable there
and randconfig builds no longer require an explicit STATIC_MEMORY=n
override to avoid a compilation error.
