Fixes #3264

I'm trying to allow a lambda function in another account to be able to invoke my CDK generated lambda function. This works through the CLI like so:

aws lambda add-permission --function-name=myFunction --statement-id=ABoldStatement --action=lambda:InvokeFunction --principal=arn:aws:iam::{account_id}:role/a_lambda_execution_role

But CDK doesn't seem to allow me to add an ArnPrincipal doing something like this:

myFunction.grantInvoke(new iam.ArnPrincipal(props.myARN))

With the error:

Invalid principal type for Lambda permission statement: ArnPrincipal. Supported: AccountPrincipal, ServicePrincipal

This PR allows ArnPrincipal to be passed to lambda.grantInvoke.

There might be some additional validation required on the exact ARN as I believe only some ARNs are supported by lambda add-permission

* chore: update package-lock.json

* feat(eks): define kubernetes resources

This change allows defining arbitrary Kubernetes resources within an EKS cluster.

* nice!

* update readme

* Update README.md

* feat(events): ability to add cross-account targets (#3323)

This adds the capability of adding a target to an event rule
that belongs to a different account than the rule itself.
Required for things like cross-account CodePipelines with source actions triggered by events.

* chore(ci): add mergify config file (#3502)

* chore: update jsii to 0.14.3 (#3513)

* fix(iam): correctly limit the default PolicyName to 128 characters (#3487)

Our logic for trimming the length of the default IAM policy name was not working,
as it wasn't updated when logicalId became a Token rather than a literate string,
and so it was never actually triggered
(it just checked that the display name of the Token was less than 128 characters,
which it always is).
The fix is to resolve the logical ID Token before applying the trimming logic.

Fixes #3402

* v1.3.0 (#3516)

See CHANGELOG

* fix: typo in restapi.ts (#3530)

* feat(ecs): container dependencies (#3032)

Add new addContainerDependencies method to allow for container dependencies
Fixes #2490

* feat(s3-deployment): CloudFront invalidation (#3213)

see #3106

* docs(core): findChild gets direct child only (#3512)

* doc(iam): update references to addManagedPolicy (#3511)

* fix(sqs): do not emit grants to the AWS-managed encryption key (#3169)

Grants on the `alias/aws/sqs` KMS key alias are not necessary since the
key will implicitly allow for it's intended usage to be fulfilled (as
opposed to how you have to manage grants yourself when using a
user-managed key instead).

This removes the statement that was generated using an invalid resource
entry.

Fixes #2794

* fix(lambda): allow ArnPrincipal in grantInvoke (#3501)
