[I] TableMigration: Add multiple prefix support for rewriteLocationPrefix API [iceberg]

krisnaru opened a new issue, #14318:
URL: https://github.com/apache/iceberg/issues/14318

   ### Feature Request / Improvement
   
   ### Overview
   
   Enhanced Apache Iceberg's RewriteTablePathSparkAction to support multiple source-target prefix pairs through a fluent chaining API, enabling complex table migration scenarios with hierarchical path mappings.
   
    ### Problem Statement
   
    The original implementation only supported a single source-target prefix pair, limiting users to simple one-to-one path transformations. This was insufficient for:
     - Multi-cloud migrations with different storage systems
     - Complex data reorganization with multiple path hierarchies
     - Cross-environment moves requiring multiple prefix mapping
     - Multiple hadoop clusters support
   
   ### Usage
   
     // Before: Single prefix only
     .rewriteLocationPrefix(sourcePrefix, targetPrefix)
   
     // After: Chainable multiple prefixes
     .rewriteLocationPrefix("s3://old-bucket/", "s3://new-bucket/")
     .rewriteLocationPrefix("hdfs://cluster/", "s3://data-lake/")
     .rewriteLocationPrefix("/tmp/", "s3://staging/")
   
   
   
   ### Query engine
   
   Spark
   
   ### Willingness to contribute
   
   - [x] I can contribute this improvement/feature independently
   - [x] I would be willing to contribute this improvement/feature with guidance from the Iceberg community
   - [ ] I cannot contribute this improvement/feature at this time

   > @krisnaru Do the files with different prefixes belong to one table?
   
   Yes. For one table.

   @krisnaru Do the files with different prefixes belong to one table?
