[JENKINS-73453] make icons in table buttons resizable

[mawinter69]

With #9131 the css class jenkins-table__button was replaced at certain places with jenkins-button. But this change caused regressions:

• The icon size for large table was almost the same as that for medium tables
• The icons wrapped in jenkins-button were not resizable
• with small table the buttons overflowed the table cell

Before:

After:

This change restores the old icon size for large tables and adds additional css rules for jenkins-button inside tables so they are properly resized and the padding is correct

See JENKINS-73453.
