aws-s3-bucket-deployment: lazy values do not work with Source

[agdimech]

Describe the bug

When using a Lazy value for any of the Source inputs, they are getting resolved immediately due to bind happening in construction. i.e:

Source.jsonData(
  DEFAULT_RUNTIME_CONFIG_FILENAME,
  Lazy.any({provide => someValue})
)

We should be able to support synthesis time values here also by delaying the source binding until synthesis time.

Expected Behavior

Lazy values should work when passing them in as Sources to the BucketDeployment

Current Behavior

They are evaluated immediately.

Reproduction Steps

Source.jsonData(
 'myfile.json,
  Lazy.any(produce: () => {console.log('getting called before synth'); return {deferred: 'value'}})
)

Possible Solution

We should be able to support synthesis time values here also by delaying the source binding until synthesis time.
