  [LLD][ARM] Allow R_ARM_SBREL32 relocations in debug info (#116956)

The R_ARM_SBREL32 relocation is used in debug info for ARM RWPI
(read-write position independent) code. Compiler-generated DWARF info
will use an expression to add the relocated value to the actual value of
the static base (held in r9) at run-time, so it should be relocated as
if the static base is at address 0.
