LOG: [BinaryFormat][ELF] Rename machine type INTEL205 to INTELGT (#159791)

`EM_INTEL205` was renamed to `EM_INTELGT` (ref
[here](https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=7b9f985957798ba4dacc454f22c9e426c6897cb8))
and is used for Intel GPU images.

We will be using this type for offloading to Intel GPUs.
