Remove generic builder pattern from element metadata creation (Part 1)

[twsouthwick]

This is part of what will probably be a few PRs to replace the generic builder pattern in use for defining element metadata. This causes a lot of JITing to occur and causes the ballooning of AOT builds.

Looks like around 5% faster while doing a file read and has removed about 25% of the generic types
