hw/arm, loongarch: Move load_image_to_fw_cfg() to common location

load_image_to_fw_cfg() is duplicated by both arm and loongarch. The same
function will be required by riscv too. So, it's time to refactor and
move this function to a common path.

- *                  data under, with fw_cfg_add_i32().

- * @image_name:     The name of the image file to load. If it is NULL, the
- *                  function returns without doing anything.
- * @try_decompress: Whether the image should be decompressed (gunzipped) before
- *                  adding it to fw_cfg. If decompression fails, the image is
- *                  loaded as-is.

- * In case of failure, the function prints an error message to stderr and the
- * process exits with status 1.
