Change the initialization time of Radio button's isChecked

Change the initialization time of Radio button's isChecked in CalculatorProgrammerRadixOperators

Fixes #1303

Description of the changes:

• Remove checkDefaultBitShift
• Add a member variable for saving what is selected
• Modify XAML

How changes were validated:

• Manual tests / Check that graph theme is unchanged
• Default Unit Tests (Unit Test pass, UI Test Fail, but it seems to be a bug because the master branch fails too )

Information

As a result of analyzing the call point of g.hpp made from C++, it was confirmed that the theme radio button in Graphing Setting is changed suddenly when CalcuatorProgrammerRadixOperators is initialized.
It was determined that there was something wrong with the components of the CalacuatorProgrammerRadixOperators, and after various tests, it was confirmed that there was a problem in the initialization of the Radio Button (BitshiftFlyout).

The problem I am assuming is as follows.

1. The radio box group does not exist.
2. Arithmetic Shift Button of Bitshift Flyout Radio Box is checked at startup.
3. When the view is converted and the CacluatorPrgrammerRadixOperators are created, the Graph Setting does not disappear and remains in the memory (Graph Setting seems to be generated by Code-base, not XAML).
4. Since other Radio Button is selected, Radio Button of Graphing Setting is Unchecked.

• Excepted
  

• Error
  

I chose a simple way to check the radio button when displaying the BitShiftFlyout.

So, I added a member variable for saving what is selected. (I just use the reference of radio directly, not use others like enum. this is dangerous?)

I don't think this is the best way. I think this is not a fundamental solution
However, to solve the problem without structural changes (or changing the internal operation), I selected this way.

The code was modified as the master branch was changed.
I added a string type, instead of reference type, member variable for saving what is selected. Because some string member variable is in the master branch now.

Thanks for the fix! I would like to better understand the underlying issue and see if we can tackle the root cause of it, your fix is a good work around to the issue, let me know what you think of my suggestions! Thanks again!

One more change I noticed and then it should be good to go!
