Migrates all security and spaces usage of deprecated Eui Page components (#167078)

Closes #161419

## Summary

Replaces deprecated EuiPage*_Deprecated components with the suggested
replacement components (see
[issue](https://github.com/elastic/kibana/issues/161419)).

### Visual Difference
The only UI that is noticeably affected is the User Profile page. The
spacing and header font size are slightly different from the previous
implementation, however, it is consistent with other
`Eui/KibanaPageTemplate` pages.

New render:
