[JS] Add hostConfig to adaptivecards-react project

[licanhua]

In #6145, adaptivecards-react is added, and which implemented HostConfigContext, but user has to implement its own Provider to customize the hostConfig.

In this PR, it allows react to pass hostConfig from props.
hostConfig takes high priority than customized host config Provider if both hostConfig and provider are used.

Fix #6504

Hi @licanhua. Thanks for helping make the AdaptiveCards JS renderer + tooling better. As additional verification, once the JS build succeeds, please go to the test site to test out your website/designer changes.

This change shouldn't be necessary as the host config is meant to be made available via the React context provider HostConfigContext. I could see it being convenient to be able to pass in a host config directly (perhaps as a component level override?). @paulcam206 what do you think?

I would like to make adaptivecards-react very simple and it's just a wrapper of adaptivecards. For advanced feature, we can provide HOC, subclass or composition. For example: AdaptiveCardsWithContext
