 Linker: ARM: Refactor relocation handling

 This refactors handling of R_ARM_CALL, R_ARM_JUMP24, R_ARM_MOVW_NC, and
 R_ARM_MOVT relocations to follow the LLVM LLD implementation. The "ELF
 for ARM"  specification is (like most documents of this type, sadly) a
 bit vague in some areas, so it seems safest to follow the behavior of a
 trusted implementation like LLD, which is remarkable in its clarity..

 Moreover, we now throw a proper error message when a jump to a symbol
 extra is out of range. This is great improvement over the previous
 behavior, which ended in a segfault.

 See #11340.
