Fixing issue where toolbar and status bar icons would be black on dar…

Fixing issue #6274. Mostly only modifications in ToolbarIconTintManager. However, I needed to upgrade the AndroidX Core dependency due to a bug in older versions where the status bar color would not change.(see google/accompanist#949 (comment) for reference).

@keunes is this PR what you had in mind for the issue?

It's better, but not ideal yet:

The notification bar (in the light theme) changes colour in time. But the top app bar (hamburger menu, search button, etc) overlap still with the podcast info (cover image + title). Only when the other icons (settings, info, filter) touch the app bar, the app bar gets a background:

I think to make the whole look smooth, we should make the background image go all the way to the top, show the app top bar background colour as soon as the cover image & title hit its area, and only at that point change the colour of Android's notification bar (from white to grey, in the light theme).

So you mean, we should change the background color of the status bar and the action bar rather than the tint of the icons? @keunes

I will take a look and check if thats the better alternative. But of course that would help to avoid the white-over-white issue as in the images you've shown above.
