Revert "Expose configuration to ignore EpoxySwiftUIHostingController safe area"

[bryankeller]

This reverts #161, which is not needed thanks to the existence of the epoxyLayoutMargins modifier.

// MARK: - View

extension View {
  /// Applies the layout margins from the parent `EpoxySwiftUIHostingView` to this `View`, if there
  /// are any.
  ///
  /// Can be used to have a background in SwiftUI underlap the safe area within a bar installer, for
  /// example.
  ///
  /// These margins are propagated via the `EnvironmentValues.epoxyLayoutMargins`.
  public func epoxyLayoutMargins() -> some View {
    modifier(EpoxyLayoutMarginsPadding())
  }
}

We can go back to always forcing EpoxySwiftUIHostingView to ignore safe area insets. Anyone who wants a bar to go into the safe area region can do so using epoxyLayoutMargins.

Note: We can't apply epoxyLayoutMargins automatically for bars because the exact position that the padding is inserted is view-specific. For example, people probably want to use the epoxyLayoutMargins modifier before a background modifier.
