R: @Abacn as this PR was split out from #40142 to isolate the load test changes. Notice that the new GCS load test has not yet been hooked up to the github workflow https://github.com/apache/beam/blob/master/.github/workflows/beam_PostCommit_Java_IO_Performance_Tests.yml. We should set up a new workflow to sweep the configuration matrix and capture regressions across different settings. |

Description
This PR adds a dedicated GCS load test for
ParquetIOand shared test infrastructure for parsing, collecting, and formatting GCS performance metrics in integration load tests:ByteSizeUtilsinit:common: Utility class to parse human-readable byte sizes (e.g.,100MB,2.5GiB,500KB) intolongbytes, and format byte counts back into readable strings.GcsIOLoadTestBase: Shared base class for GCS file-based I/O load tests extendingIOLoadTestBase. Extracts GCS performance metrics (gcs_op_*,gcs_http_read_*,gcs_http_write_*) from pipeline results and formats them.ParquetIOLT: IntroducesParquetIOLTinit/google-cloud-platform, testing write, read, and write-then-read performance against GCS usingParquetIO.
