[WebAssembly] Rename functions in wasm-eh.cpp (#130220)

I think it is generally better for tests have some descriptive function
names so that we can insert new tests in the middle and don't have to
renumber all tests.

Also recently I added a (named) test to this file in #129020 so I think
it's consistent for other tests to be named.
