[SHELL32] Fix Control_RunDLLW (#5400) 
This commit makes Control_RunDLLW pass all but one tests from rostests (the one test that fails is the first one, but it only fails if the path to the test program contains a space).

- Rework string parsing in the Control_DoLaunch routine
- Do not send the CPL_STARTWPARMSW message, if no extra parameters were specified (fixes the failing Got NULL lParam2! and some CPL_STARTWPARMSW: expected -1 got %d tests)
- Do not resolve invalid dialog names to index zero, unless the name is empty (fixes some of the failing CPL_DBLCLK: expected -1 got %d tests)
- Handle quotes in the second part of wszCmd
