Implemented GUI CLI arguments for specifying a smartcard

[Spamtributor]

Implemented GUI CLI arguments for specifying a smartcard in challenge-response mode to use for unlocking a database.

Resolves: #12528

I achieved this by first adding optional smartcard arguments to the entry point of the GUI application before passing it down the call stack all the way to "DatabaseOpenWidget::buildDatabaseKey" and then performing the challenge response procedure both in exactly the same way as the pure CLI.

Usage:

KeePassXC --yubikey 1:12345678 Passwords.kdbx

Testing strategy:

I didn't implement test cases for this new feature because the GUI CLI scope was already uncovered by the existing test cases and was therefore unsure how to proceed however I ran the existing tests and received the same results before and after my modifications as well as tested the following cases, if this is a issue I will be happy to ablidge:

• Failing to unlock a database with a invalid smartcard argument.
• Unlocking a database with a valid smartcard argument.
• Failing to unlock a database with a valid smartcard argument due to it not being connected.
• Failing to unlock a database with a valid smartcard argument due to failing to press the touch sensor.
• Failing to unlock a database with a valid smartcard argument due to it not needing one.

Type of change:

• ✅ New feature (change that adds functionality)
