Apply theme and acrylic changes without restart

[tsvietOK]

Little bit increased acrylic opacity
Some code cleaning
For idea thanks to Microsoft
Known bugs:
Sometimes the theme of datagrid is not updated
May be some freeze while changing theme

[yaira2]

Can you keep the acrylic opacity the same as it was before?

@yaichenbaum Let's compare:
Before:


After:

@tsvietOK I tested it myself, the first one is cleaner.

[tsvietOK]

@yaichenbaum As you wish

[yaira2]

If people really want we can add in a way to adjust it but I think that is taking it too far.

[tsvietOK]

@yaichenbaum For some reason ModernNavigationToolbar exists at home page, do you have the same problem?
Edit: It is not part of this PR

[yaira2]

@tsvietOK What is the issue you are seeing?

[tsvietOK]

@yaichenbaum As you can see an screenshots above, bottom tool bar present at home page

[yaira2]

@tsvietOK I do not see that, but I will test again.

[yaira2]

@tsvietOK I don't see that issue.

[tsvietOK]

@yaichenbaum I have found it. This caused by 8f3083d
And this bug is language dependent. If i change var tabLocationHeader back to "New tab", toolbar invisible at home page.

[tsvietOK]

As i understand, home page detection based on "New tab" string

[yaira2]

@tsvietOK To fix that we just need to update the check when navigating to a page to use the resource string.

@yaichenbaum Your changes fixes this bug.
