Make scanner profile form composable

Related issue - #325238 (closed)

What does this MR do?

This MR makes the DAST scanner profile form reusable / composable, as we plan to include the form inline in another place (which is DAST Scans form). The main idea is to create success and cancel event handles, move the form actions outside the component and let the parent handle it.

It also

• adds an optional showHeader prop, which will be used later
• make the submit button enabled always to conform with the design specs

More importantly, this also adds feature specs for DAST Scanner Profile form to make sure there is no regression during this refactor and for future coverage as well

Screenshots (strongly suggested)

No visual changes except that submit button is enabled always

Local testing

Navigate to the DAST Scanner profile form in your GDK /:namespace/:project/-/security/configuration/dast_scans/dast_scanner_profiles/new
