Samar Sunkaria 8ffee678c6 Add support for R_ARM_REL32 relocations. (#3631)
It is fairly straightforward to correctly resolve an R_ARM_REL32 relocation as described in
in the "Relocation types" section of ARM ELF Specification
(https://developer.arm.com/documentation/espc0003/1-0/?lang=en). The documentation provides
the following formula:

```
S - P + A
```

where `S` is the value of the symbol (symAddr), `P` is the address of the place being
relocated (relAddr), and `A` is the addend (value extracted from the storage unit being
relocated, in this case).

I encountered the R_ARM_REL32 relocation type as part of my work for building apps written
in Swift for the Flipper Zero. I have manually tested that this relocation works correctly
by building and running multiple apps that depend on this relocation.
