  [lldb][ObjectFileELF] Support AArch32 in ApplyRelocations

Allow the ObjectFileELF plugin to resolve R_ARM_ABS32 relocations from AArch32 object files. This fixes https://github.com/llvm/llvm-project/issues/61948

The existing architectures work with RELA-type relocation records that read addend from the relocation entry. REL-type relocations in AArch32 store addend in-place.
The new function doesn't re-use ELFRelocation::RelocAddend32(), because the interface doesn't match: in addition to the relocation entry we need the actual target section memory.
