chore: Add display contents to runtime drawer wrapper

[jkuelz]

Description

Prep for a fix to make drawer content to extend full height.
This change has uncovered a few issues:

1. Other components which used this wrapper were unintentionally affected by this change (see screenshot approval 40eb2153-dfbe-4dba-aa83-28f65c5474e1). This is being solved in chore: Fix code reuse between app layout and alert/flashbar runtime API #2963, which needs to be merged before this one, and this will require a rebase.
   
2. Webdriver is seemingly unable to access text that are direct children of display: contents, when a parent has overflow: hidden applied (which is the case for drawers).

<div id="one" style={{overflow: 'hidden'}}>
    <div>Ok</div> // findable
    <div style={{display: 'contents'}}>Does not work</div> // not findable
    <div style={{display: 'contents'}}>
        <span>Also works</span> // findable
    </div>
</div>
<div id="two" style={{display: 'contents'}}>  // findable
    This works
</div>

Both of these issues were originally solved another way #2924, which presented other issues mentioned there.
Since then, it has been decided that these failed tests is a bug in Webdriver, not our tests or implementation. To make these tests pass, two options were presented:

• Option 1 Updating the dev page (ended up going in this direction)
• Option 2 Updating the test itself

How has this been tested?

Ran through dev pipeline.
