wslc: add --workdir/-w support to container create and run

[ptrivedi]

Summary

• Extends the --workdir/-w flag (already supported by container exec) to container create and container run
• Passes the working directory through ContainerService::CreateInternal to the container launcher via SetWorkingDirectory()
• Adds CLI parse test cases, unit tests (long option, short option, empty-value rejection), and E2E tests for both commands

Test plan

• Unit tests: *WSLCCLIExecutionUnitTests* — covers RunCommand_ParseWorkDir* and CreateCommand_ParseWorkDir*
• E2E tests: WSLCE2E_Container_Create_WorkDir, WSLCE2E_Container_Create_WorkDir_ShortAlias, WSLCE2E_Container_Run_WorkDir, WSLCE2E_Container_Run_WorkDir_ShortAlias
• CLI parse tests: CommandLineParsingTests via CommandLineTestCases.h entries
