This adds the ProfileDialogView to storybook pages
For now, there's just one control to switch between own profile and
another profile; more to come in later PRs.
The mocked global objects (mainModuleInst and globalUtilsInst) are
injected via QML
Fixes: #7820
In comparison to generic page-wise hot reloading, this technique
requires using dedicated component within a storybook page but
provides greater flexibility e.g. preserving component state across
source reloads.
Closes: #7975
