Add bytecode test for compare_type attr. (#174)

There is currently no bytecode test for `compare_type` in CHLO. See [coverage report](https://htmlpreview.github.io/?https://raw.githubusercontent.com/GleasonK/stablehlo/ccov/reports/ccov_2022_09_21_14-51-15/stablehlo/dialect/ChloBytecode.cpp.gcov.html).
