[I] Support fs.s3a.auth.profile.name and fs.s3a.auth.profile.file for ProfileCredentialsProvider [datafusion-comet]

URL: https://github.com/apache/datafusion-comet/issues/4245

   ### What is the problem the feature request solves?
   
   Follow-up to #4212 / #4213.
   
   #4213 added support for mapping `ProfileCredentialsProvider` to the AWS profile credential chain in the native `object_store`-based S3 reader, but it does not currently honor the Hadoop S3A configuration options:
   
   - `fs.s3a.auth.profile.name` — selects the named profile to load
   - `fs.s3a.auth.profile.file` — points to an alternate AWS credentials file
   
   These are recognized by Hadoop's `org.apache.hadoop.fs.s3a.auth.ProfileAWSCredentialsProvider` (introduced in Hadoop 3.4.2). Per discussion on #4213 with @parthchandra, the native side should resolve these configs itself (similar to how `AssumedRoleCredentialProvider` and `SimpleAWSCredentialsProvider` already do), so the behavior is independent of the user's bundled Hadoop version.
   
   ### Describe the potential solution
   
   Read `fs.s3a.auth.profile.name` / `fs.s3a.auth.profile.file` (with bucket-scoped overrides) in `build_aws_credential_provider_metadata` and forward them to `ProfileFileCredentialsProvider::builder()` via `.profile_name(...)` and `.profile_files(ProfileFiles::builder().with_file(Credentials, ...).build())`.
   
   ### Additional context
