[test] Port tests in test/ to test/lit/basic/ (WebAssembly#6160)

This ports all tests from `test/` to `test/lit/basic/`. The set of
commands and `CHECK` lines used are the same as the ones in WebAssembly#6159. Now
 we use `lit` to test these, this also deletes all `.wast`,
`.wast.from-wast`, `.wast.fromBinary`, and
`.wast.fromBinary.noDebugInfo` files from `test/` and all related test
routines from the python scripts.

All `CHECK` lines are generated by `update_lit_checks.py --all-items`.

This also deletes these three multi-memory tests in `test/lit/`, because
they seem to contain the same code with the ones in `test/`, which have
been ported to `test/lit/basic/` along with other tests.
- `test/lit/multi-memories-atomics64.wast`
- `test/lit/multi-memories-basics.wast`
- `test/lit/multi-memories-simd.wast`

This also adds newlines between `(func`s in case there are none to make
`CHECK` lines easy to view, and removes some extra existing newlines
here and there.
