set the eval branch quota in the return type block

`prepare` and `prepareWithDiags` parse the query at comptime in the
return type definition.

This exceeds the branch quota since https://github.com/ziglang/zig/commit/b11ac9c5bfb4048eb4aa561f8b3b058a76787f7e.
Use a block and `@setEvalBranchQuota` to work around this.

Fixes #30.
