Revert moving things to Ruby

This is slowing down benchmarks on x86, so lets revert it for now.

Fix the return value of `Integer#downto` called with a block

2024-07-04T03:11:12+00:00

As the document states, it should return `self`, not `nil`.

Speeds up ChunkyPNG.

The interpreter is about 70% faster:

```
before: ruby 3.4.0dev (2024-07-03T15:16:17Z master 786cf9db48) [arm64-darwin23]
after: ruby 3.4.0dev (2024-07-03T15:32:25Z ruby-downto 0b8b744ce2) [arm64-darwin23]

----------  -----------  ----------  ----------  ----------  -------------  ------------
bench       before (ms)  stddev (%)  after (ms)  stddev (%)  after 1st itr  before/after
chunky-png  892.2        0.1         526.3       1.0         1.65           1.70
----------  -----------  ----------  ----------  ----------  -------------  ------------
Legend:
- after 1st itr: ratio of before/after time for the first benchmarking iteration.
- before/after: ratio of before/after time. Higher is better for after. Above 1 represents a speedup.
```

YJIT is 2.5x faster:

```
before: ruby 3.4.0dev (2024-07-03T15:16:17Z master 786cf9db48) +YJIT [arm64-darwin23]
after: ruby 3.4.0dev (2024-07-03T15:32:25Z ruby-downto 0b8b744ce2) +YJIT [arm64-darwin23]

----------  -----------  ----------  ----------  ----------  -------------  ------------

chunky-png  709.4        0.1         278.8       0.3         2.35           2.54

Use `defined?(yield)` and `SIZED_ENUMERATOR`

Prefer built-in features over method calls that may be overridden.
