Add --experimental_exec_configuration_distinguisher This work is cleaved off from the --experimental_output_directory_naming_scheme work (see https://github.com/bazelbuild/bazel/issues/14023) and is meant as a less-exotic (and more quickly deployable) way to fix-up potential action conflicts due to insufficient configuration distinguishing in or around the exec transition. The following modes are added: legacy: Keep current behavior of only setting platform_suffix to exec-%X where %X is a hash of the current execution platform. fullHash: Set platform_suffix to exec-%X where %X is a hash of the entire post-configuration transition (although, with platform_suffix emptied, to prevent self-referential hashing headaches). diffToAffected: Set platform_suffix to exec (only for ease in reading output paths) and update `affected by Starlark transition` with all changed options. This effectively treats the exec transition like a Starlark transition. off: Do not touch platform_suffix or do any other work inside the execution transition to ensure distinguished configurations. This is expected to be used with --experimental_output_directory_naming_scheme as part of removing these local configuration distinguishers in favor of a global system. PiperOrigin-RevId: 433839227
{Fast, Correct} - Choose two
