lib/stack: Restrengthen base_address

commit a1f2b0e1efd5 ("treewide: lib/stack: Make base_address arch
specific") made base_address() a weak function in order to allow
architectures to override it. Linking for EFI doesn't seem to figure
out the right one to use though [anymore?]. It must have worked at
one point because the commit calls outs EFI as the motivation.
Anyway, just drop the weakness in favor of another HAVE_ define.

treewide: lib/stack: Make base_address arch specific

Calculating the offset of an address is image specific, which is
architecture specific. Until now, all architectures and architecture
configurations which select CONFIG_RELOC were able to subtract
_etext, but the EFI configuration of riscv cannot (it must subtract
ImageBase). Make this function weak, such that an architecture may
override it when necessary, to accommodate the image layout. Then,
immediately supply the riscv override.

lib/stack: print base addresses on relocation setups

Making sense from dumped stacks when running EFI tests is very hard due
to the relocation. Fix it by adjusting the address back to the original
address.

Introduce CONFIG_RELOC, which would be set on arm64 and on EFI configs.

Frame stack walker is just a stub on arm and ppc.
