Add a "canExec" method to SpawnActionContext and SpawnRunner.

This is used by the ProxySpawnActionContext to determine at runtime
whether a spawn strategy can execute a given spawn.

Adds the flag --incompatible_list_based_execution_strategy_selection,
which is used to make this an opt-in change that will be managed by the
incompatible flags process.

The flag's GitHub issue is here:
https://github.com/bazelbuild/bazel/issues/7480

RELNOTES[INC]: The flag --incompatible_list_based_execution_strategy_selection
was added and is used to ease the migration to the new style of specifying
execution strategy selection and fallback behavior. The documentation for
this flag is here: https://github.com/bazelbuild/bazel/issues/7480
