Install of PHP 7.2.34 fails on M1 Macbook

With all the right homebrew packages in place, this error ends up blocking an install.

```
> asdf install php 7.2.34

I found reference to the same error here: https://github.com/henkrehorst/homebrew-php/issues/134

The fix includes passing a flag `-DU_DEFINE_FALSE_AND_TRUE=1`

I have tested and this does appear to fix. I'll submit a PR. Untested on any other systems / installs though, so please test before merging.

Start by reproducing `asdf install php 7.2.34` on an M1 Mac and inspect the failure in `ext/intl/collator/collator_sort.c`, where `TRUE` and `FALSE` are undeclared. Verify the reported `-DU_DEFINE_FALSE_AND_TRUE=1` configuration change and confirm the install succeeds without breaking other systems.
