We just didn't consider the shared credentials file as returned by the SDK when loading configuration.

Closes #32130.

Exemption from integ because unit tests cover the offending code.

AWS CLI does:

  • If --profile: credentials profile > config profile > no region
  • If not --profile: credentials default > config default > no region

No region behaves as follows:

  • Global services work (IAM, S3, Route53)
  • Regional services fail with an error, saying you must specify a region

Traditionally, CDK has defaulted to us-east-1 in this case. I'm like 90% sure we used to do that to copy the AWS CLI, I wonder if they changed their behavior when migrating CLIv1 -> CLIv2

Also CDK traditionally had the behavior that if the profile doesn't have a region, we will take the region from the [default] profile, but apparently the CLI doesn't do that.

EDIT: Ohh, AWS CLIv2 now has a magic aws-global region, that they default to.

…32134)

In Node.js, if you assign `undefined` to an environment variable, that variable ends up having the string `"undefined"`.

If we are using IAM user credentials, `AWS_SESSION_TOKEN` should not be set, but because we were not handling this edge case, it was getting assigned an invalid value:

```
Welcome to Node.js v22.9.0.
Type ".help" for more information.
> process.env.AWS_SESSION_TOKEN || process.env.AMAZON_SESSION_TOKEN
undefined
> process.env.AWS_SESSION_TOKEN = process.env.AWS_SESSION_TOKEN || process.env.AMAZON_SESSION_TOKEN
undefined
> process.env.AWS_SESSION_TOKEN
'undefined'
```

Closes #32120.

### Reason for this change

We don't need to use the third party `source-map-support` package anymore to achieve the same result.

### Description of changes

We use `process.setSourceMapsEnabled(true)` instead. However unlike the previous package, this command needs to be run _before_ we import any other files, otherwise it won't work. We therefore move it into the executable.

### Description of how you validated changes

Manual verification
