[Payment Mod]Upgrade Stripe to support SCA (PSD2 regulation)

[pH-7]

In order to support the new SCA payment regulations, it will be necessary to migrate the current Stripe version to the newer one.

TODO:

• Cleanup Stripe code in the payment module. Remove redundant things in there.
• Migrate all Stripe code present in the payment mod to Stripe JS v3 and to Stripe PHP, SDK 7.3+.

$intent = \Stripe\PaymentIntent::create([
        'payment_method_data' => [
            'type' => 'card',
            'card' => ['token' => $token_id],
        ],
        'amount' => $amount,
        'currency' => 'usd',
        'confirmation_method' => 'manual',
        'confirm' => true,
    ]);

Might be worth to consider Omnipay, https://github.com/thephpleague/omnipay-stripe And, it will make things easier, as the number of supported gateways in pH7Builder has increased in the past few years.
