Add missing isSelected command to new Element API

[garg3133]

Description of the bug/issue

The isSelected command is currently missing from the new Element API. To support this command, a new file named isSelected.js needs to be added inside lib/api/web-element/commands directory, whose content should be similar to the get* command files present in the same directory.

The argument passed to this.runQueuedCommandScoped in these files is the name of the corresponding method to be called from the lib/transport/selenium-webdriver/method-mappings.js file.

Steps to reproduce

Go to any test file and try to add const result = await browser.element('<selector>').isSelected() and then run the test. This would result in an error right now, while if you replace isSelected() with getText(), it should work fine.

After adding the command implementation, the .isSelected() command should work fine and return a boolean promise.

TODO

• Add missing command
• Fix JSDoc of the command
• Add tests for the new command
• Add types for the new command

[garg3133]

Assigning this to @dikwickley since they already have a PR on this which seems to be almost complete (just the tests are remaining).
