refactor(build)!: move build from types and nest the object

[ecrupper]

Follow up from #1106, #1095, and #997

Of note:

• Migrated the inline types for database resources (i.e. type Build struct inside database/build/build.go) to a database/types package. This was sad but necessary due to import cycles when attempting to leverage Gorm SQL migration in the tests.
• Created a testutils/api_resources.go file. This was to prevent the duplication of API object instantiation that existed across the database package for testing.
• continued to prune cases where we only brought in the repo object because it had info tied to a build we wouldn't have had previously. Notable exception is compiler engine because we can compile without a build.
• ListBuildsForDashboardRepo does not include repo preloading because I didn't see the point. Would not mind changing that if someone preferred it.

nice. some minor things. tested locally with WIP branches in sdk-go + worker. will need some tweak in UI to be able to parse new response, but looks good otherwise.

ListBuildsForDashboardRepo does not include repo preloading because I didn't see the point. Would not mind changing that if someone preferred it.

tripped me up at first, but i think it makes sense the way it is
