fix(button): update button sizes in icon only to have a minimum width

[booc0mtaco]

Previously, the button styles when icon-only would unset the minimum width to take on a perfectly circular shape. This is fine in default cases, but would cause the button to lose width when used in a flex context, like in DataTable. Instead of unsetting the width for icon-only, add a min-width to each button size when layout is icon-only.

Test Plan:

• Wrote/updated automated tests
• CI tests / new tests are not applicable
• Manually tested my changes, and here are the details:
  • validate no snapshot changes occurred

Just a couple minor comments. Beyond that, I'll leave it up to you whether the changes seen in Chromatic are good.

Turns out those two snapshots had a hidden example of the same issue seen in the sort buttons used in the DataTable :D harder to see since the VERY edge of the X close buttons was close to being trimmed
