microG Settings integration, icon/activity changes

[Nanolx]

Follow up for #765

• separates launcher icon from main activity (so it can be disabled without making microG inaccessible, think of Launchers that don't allow to hide Apps on their own)
• fix issue Fix icon being not displayed on some devices #758 (launcher icon not shown on all devices)
• microG Settings in AppInfo and SystemSettings (+ adaptive icon) #719 added 'microG settings' to System Settings > Device, move into System Settings directly (result may vary, depending on the ROM and Android Release)
• improved version of the microG icon for System Settings

It will be interesting to try something like this:
android:enabled="@bool/is_alias_enabled"
then add <bool name="is_alias_enabled">true</bool> to bools.xml
and create ../values-v23/bools.xml with this

<?xml version="1.0" encoding="utf-8"?>

    <bool name="is_alias_enabled">false</bool>

So launcher icon should be always disabled Android 6.0 and newer.
Settings integration is available starting from this android version.

Honeslty I think that can be still visible, is a shortcut, wothout go on settings>system>microg.
For the same reason I have installed an app to open update on lineageos.

Hello @Nanolx

Maybe you can find time to update this pull request?
A lot of things have changed.

[Nanolx]

I'll have a look at it next week.

Did this slip through the cracks? This would be super nice to have 👀

@Nanolx, I don't know if you're free to be able to look into this right now or not. But if possible, it'll be much appreciated. Sorry if I bothered you.

This PR is obsolete because most of its stuff is already merged separately in microG.

[ILoveOpenSourceApplications]

Ah, I see you took it into your own hands and did #2042 & #2061. I did check for any similar PRs, but didn't check thoroughly, my bad. But then, why leave this open still, given that it's obsolete now?

Edit: On a similar note, is #1489 also obsolete?

[ale5000-git]

How I have said "most of its stuff is already merged separately in microG" but probably there is still a small part that isn't, but it need to adapted to the latest code of microG and I don't have time currently.

About #1489 probably yes since the icon of microG got changed in the meantine but I don't have time to check carefully the PR now.
