This pull request introduces several enhancements and fixes to the rspack-test-tools package, focusing on improved handling and output of compiler statistics. The most important changes include the addition of new types for multi-stats, updates to various processors to handle these types, and the introduction of new configuration options for writing stats output and JSON files.

Enhancements to Compiler Statistics Handling:

• Added new types TCompilerMultiStats to handle multi-stats for both Rspack and Webpack compilers. (packages/rspack-test-tools/etc/test-tools.api.md [1] packages/rspack-test-tools/src/type.ts [2]

• Updated ITestCompilerManager interface to return TCompilerStats or TCompilerMultiStats in the getStats method. (packages/rspack-test-tools/etc/test-tools.api.md [1] packages/rspack-test-tools/src/type.ts [2]

Processor Updates:

• Modified BasicProcessor, HashProcessor, HotSnapshotProcessor, SimpleTaskProcessor, SnapshotProcessor, StatsAPIProcessor, StatsProcessor, and WatchProcessor to handle the new multi-stats types and write stats output and JSON files based on the new configuration options.

Configuration Updates:

• Introduced new configuration options writeStatsOuptut and writeStatsJson to control the writing of stats output and JSON files. (packages/rspack-test-tools/etc/test-tools.api.md [1] packages/rspack-test-tools/src/type.ts [2]

Test Configurations:

• Updated test configurations to use the new writeStatsOuptut and writeStatsJson options.
