fix(ios): expose "sectionHeaderTopPadding" for layout backwards compatibility

[hansemannn]

JIRA:
https://jira.appcelerator.org/browse/TIMOB-28524

Summary:

• Adds property "sectionHeaderTopPadding" to ListView and TableView. Only supported on iOS 15+.
• Note that iOS 15 displays more padding above every header compared to older iOS versions.
• Setting this property to zero restored old behavior. (ie: No extra padding).

ListView Test:

1. Build and run the below on iOS 15.
2. Note the padding above the 2 section. (Looks like "issue.png" attached to TIMOB-28524.)
3. Uncomment the sectionHeaderTopPadding: 0.0 line below and re-run.
4. Notice the extra section padding is gone. (Looks like "fix.png" attached to TIMOB-28524.)

const window = Ti.UI.createWindow({ title: 'Window 1', backgroundColor: '#f0f0f0' });
window.add(Ti.UI.createListView({
//	sectionHeaderTopPadding: 0.0,
	sections: [
		Ti.UI.createListSection({
			headerView: Ti.UI.createView({ height: 10 }),
			footerView: Ti.UI.createView({ height: 10 }),
			items: [
				{ properties: { title: 'Test 1' } },
				{ properties: { title: 'Test 2' } },
				{ properties: { title: 'Test 3' } },
			]
		}),
		Ti.UI.createListSection({
			headerView: Ti.UI.createView({ height: 10 }),
			footerView: Ti.UI.createView({ height: 10 }),
			items: [
				{ properties: { title: 'Test 1' } },
				{ properties: { title: 'Test 2' } },
				{ properties: { title: 'Test 3' } },
			]
		})
	]
}));
const nav = Ti.UI.createNavigationWindow({ window });
nav.open();

TableView Test:

2. Note the padding above the 2 section. (Looks like "issue.png" attached to TIMOB-28524.)

const window = Ti.UI.createWindow({ title: 'Window 1', backgroundColor: '#f0f0f0' });
window.add(Ti.UI.createTableView({
//	sectionHeaderTopPadding: 0.0,
	data: [
		Ti.UI.createTableViewSection({
			headerView: Ti.UI.createView({ height: 10 }),
			footerView: Ti.UI.createView({ height: 10 }),
			rows: [
				Ti.UI.createTableViewRow({ title: 'Test 1' }),
				Ti.UI.createTableViewRow({ title: 'Test 2' }),
				Ti.UI.createTableViewRow({ title: 'Test 3' }),
			]
		}),
		Ti.UI.createTableViewSection({
			headerView: Ti.UI.createView({ height: 10 }),
			footerView: Ti.UI.createView({ height: 10 }),
			rows: [
				Ti.UI.createTableViewRow({ title: 'Test 1' }),
				Ti.UI.createTableViewRow({ title: 'Test 2' }),
				Ti.UI.createTableViewRow({ title: 'Test 3' }),
			]

	]
}));
const nav = Ti.UI.createNavigationWindow({ window });
nav.open();
