[Serverless] Consider --kbnAppHeadersOffset value for sticky elements and page size

[crespocarlos]

fixes 176177
relates to elastic/eui#7765

Summary

Changes the min-block-size to account for the kibanaProjectHeader element, which exists only in serverless, to calculate the page size and sticky elements' top position.

Stateful

sticky-header-stateful.mov

Serverless

sticky_serverless.mov

no_unnecessary_scroll.mov

return_to_top.mov

How to test

• Start a serverless instance
  • yarn es serverless --projectType=PROJECT_TYPE --kill --clean --license trial -E xpack.security.authc.api_key.enabled=true
• Start a local kibana
• Check if the pages still work as expected
