Fix all tests to work with squoosh (#1859)

Fixes #1834.
Set squoosh as the default renderer and update all tests to work with
squoosh. To enable this, two main changes to testing have been made.

1. Instead of testing for text existence using
onNodeWithText().assertExists(), add a new function assertHasText().
This works by adding all text rendered under a root node into a hash
stored in the root node's Modifier.semantics(). This hash is then
checked in the assertHasText() function.

2. All nodes with click/press interactions will get a Modifier.testTag()
set with its node name. Tests that perform clicks on nodes use
onNodeWithTag() instead of onNodeWithText().
