[Feature] Add a --inline-direct flag for dbt show

[dbeatty10]

Is this your first time submitting a feature request?

• I have read the expectations for open source contributors
• I have searched the existing issues, and I could not find an existing issue for this feature
• I am requesting a straightforward extension of existing dbt functionality, rather than a Big Idea better suited to a discussion

Describe the feature

Introduce a new --inline-direct flag for dbt show that:

• avoids loading the entire manifest, and
• skips rendering any Jinja templates

i.e. speed up execution time of doing the equivalent of dbt show --inline when there is no Jinja templating that is needed. For example, the following doesn't have any Jinja templating and doesn't need the manifest, so we should be able to skip both of those:

dbt show --inline-direct "select * from my_table"

Usage example

With this feature, you can call dbt show with --inline-direct rather than --inline:

dbt show --inline-direct "select * from my_table"
