System: new AccessManager for access control

[yookoala]

Description

• A new method ModuleGateway::selectRoleModuleActionNames().
• A new class Action to replace simple string $address parameter in isActionAccessible().
• A new class AccessManager to provide feature of isActionAccessible().
• Make AccessManager accessible globally as $accessManager in index.php routed scripts.
• Mark isActionAccessible deprecated.

Motivation and Context

• To replace isActionAccessible() function.
• Remove unnecessary use of global variables, $guid and $connection2.

How Has This Been Tested?

• CI environment.
• Locally.

I've changed the Action usage to use Action::fromRoute() instead of new Action() to initiate the instance. Should be more flexible for future changes.
