[WebAssembly] Update generic and bleeding-edge CPUs (#96584)
This updates the list of features in 'generic' and 'bleeding-edge' CPUs in the backend to match https://github.com/llvm/llvm-project/blob/4e0a0eae58f7a6998866719f7eb970096a2a52e9/clang/lib/Basic/Targets/WebAssembly.cpp#L150-L178 This updates existing CodeGen tests in a way that, if a test has separate RUN lines for a reference-types test and a non-reference-types test, I added -mattr=-reference-types to the no-reftype test's RUN command line. I didn't delete existing -mattr=+reference-types lines in reftype tests because having it helps readability. Also, when tests is not really about reference-types but they have to updated because they happen to contain call_indirect lines because now call_indirect will take __indirect_function_table as an argument, I just added the table argument to the expected output. `target-features-cpus.ll` has been updated reflecting the newly added features.
