visual density should not affect vertical menu padding anymore. (*)
- Some of test values (y coordinate/height) are also updated to align
with this change and also add a regression test
    - Enhance `MenuAnchor` documentation to prevent user confusion.

- Description: On desktop/web platforms, VisualDensity.compact is
applied by default, which caused the issue as reported.
Previously, this compressed menus vertically. 

In this PR:
- Vertical padding affected by visual density is removed to follow
[Material Design
specs](https://www.figma.com/community/file/1035203688168086460) so that
visual density should not affect vertical menu padding anymore. (*)
- Some of test values (y coordinate/height) are also updated to align
with this change and also add a regression test
    - Enhance `MenuAnchor` documentation to prevent user confusion.
