[POP-7487] Add materialize adapter for dbt 1.0+

[MasterOdin]

PR adds the materialize adapter as another thing we support for our dbt builds. dbt-materialize is unique in that it requires dbt-postgres to also be installed, and so that necessitated altering how build_requirements.txt worked so that I could have a way to specify "extra" requirements for certain adapters. While I initially had a way to do this in the original bash script, I figured this was getting a bit too "hairy" in terms of complex bash scripting and that it'd be hard to maintain in the future, that I also went ahead and rewrote the script to python. It ended up a bit longer, but it's far cleaner and I think easier to edit for other people, especially the lines determining what dependencies to include or not.

Note, while dbt-materialize has versions available for 0.20.0 and 0.21.0, they used exact version matching against dbt-postgres (so dbt-materialize==0.21.0 required dbt-postgres==0.21.0), which would necessitate downgrading the version of dbt-postgres@^0.21.1 we use. Given that I'm not sure the ramifications of that, and that these versions are years old and very much EOL, I figured fine to not support them unless someone explicitly asks and we can revisit then. We already also have precedent of some adapters only support 1.0+ (athena).

POP-7487 Add materialize support for dbt

What

Add support for materialize connections in dbt using the dbt-materialize adapter. This would allow materialize folks to recommend us as a cloud based editor for dbt + materialize, given that dbt Cloud does not support it.

Why

1. Strengthen relationship with materialize
2. Have feature that they do not have with dbt Cloud
