chore: Move httpapi, httpmw, & database into coderd (#568)

* chore: Move httpmw to /coderd directory
httpmw is specific to coderd and should be scoped under coderd

* chore: Move httpapi to /coderd directory
httpapi is specific to coderd and should be scoped under coderd

* chore: Move database  to /coderd directory
database is specific to coderd and should be scoped under coderd

* chore: Update codecov & gitattributes for generated files
* chore: Update Makefile
