feat: add component.type function

[timdeschryver]

This PR adds a type function to set an input's value - inspiration from https://github.com/testing-library/user-event.

For example:

const component = render(AppComponent);
component.type(component.getByTestId('input'), 'Oh, hello!');

Has some options:

• By default each char gets inputted individually but it's configurable to input the value at once with allAtOnce:

const component = render(AppComponent);
component.type(component.getByTestId('input'), 'Oh, hello!', { allAtOnce: true });

• Add a delay for each input with delay (in ms):

const component = render(AppComponent);
component.type(component.getByTestId('input'), 'Oh, hello!', { delay: 100 });
