This should make the classes (validators, trait services) visible to the assembler - but notably not making the models visible.

ok I think the easiest way to test this will be to use a custom (non-alloy) trait class in a plugin/CLI test - as proven by polyvariant/smithy4s-bsp#10 this finally allows us to use those properly. the other thing would still be nice to test though, I'll need to think of a library that we can use as the example (or make a plugin test like that somehow) |

thought: it is WAY too easy to misconfigure a transformation, hence this extra care

BTW we had no other tests that involved user-provided transformations/validators, apparently. There's no software.amazon.smithy.build.ProjectionTransformer or software.amazon.smithy.model.validation.Validator in the test resources. I think these tests suffice, but maybe we should have a more minimal one for both too?
Workaround / fix for smithy-lang/smithy#2596. Even fixes #336.
tl;dr without passing the classloader to
assembler(), we can run into strange cases where the validator gets loaded and the trait services don't - meaning the validators won't behave like they're supposed to.PR Checklist (not all items are relevant to all PRs)
