feat(medialive): new AWS Elemental MediaLive L2 Construct with integration on MediaConnect L2 alpha

[jamiepmullan]

Issue # (if applicable)

Closes #.

Reason for this change

Next AWS Elemental Media Services L2 construct alpha - with a big API surface!

Description of changes

Full new alpha module

• Lots and lots of enums and types, some were auto-generated
• As alpha grows in maturity could do with more integration tests to test further permutations
• Includes integration with aws-mediaconnect-alpha to reference more easily (also integrated with aws-mediapackagev2-alpha)
• the API surface is quite large so we're going to need to rely on API validation too

This PR also introduces an integration with aws-mediaconnect-alpha module

Describe any new or updated permissions being added

MediaLive has an auto-generated role (on channel and input) which gets permissions required. This is done inline with documentation: https://docs.aws.amazon.com/medialive/latest/ug/trusted-entity-requirements.html

Description of how you validated changes

Comparisons between validations in Console and L2
Integration tests and unit tests (more to be added with more maturity of alpha module)
