LibELF: Refactor how arch-specific dynamic relocation types are handled

We currently expect that the relocation type numbers are unique across
all architectures. But RISC-V and x86_64 use the same numbers for
different relocation types (R_X86_64_COPY = R_RISCV_JUMP_SLOT = 5).

So create a generic reloc type enum which maps to the arch-specific
reloc types instead of checking for all arch reloc types individually
everywhere.
