zcl_enums and zcl_bitmaps handle built-in types inconsistently

[bzbarsky-apple]

zcl_enums does:

          queryZcl
          .selectAllEnums(this.global.db, packageId)
          //Filtering out all atomic enums
          .then((es) =>
            es.filter((e) => !e.name.toLowerCase().match(/^enum\d+$/g))
          )

zcl_bitmaps just does:

        queryZcl.selectAllBitmaps(this.global.db, packageId)

so the latter will iterate over things like bitmap8 and whatnot.
