Use `getElementAsAPInt(`) to read array elements and emit via `addIntAsBlock()` which handles target endianness correctly, instead of `getRawDataValues()` which exposes host endianness. This fixes test failures on big-endian hosts cross-compiling for little-endian targets. Reland of #182442 with endianness fix.
