fix: create kvdb arch workspace packages before yarn install

npm_install_deps does a clean 'yarn install --immutable' on a cache miss; the
@aztec/kvdb-<arch> optionalDependencies must resolve to the local ts/packages/*
workspaces (created by prepare_arch_packages) or the install 404s against npm.
Run prepare_arch_packages before npm_install_deps.
