[TASKMGR] Slightly smaller left border in 1st page "Apps", and 2nd page "Processes"

Reduce the left border a bit for the 1st and 2nd page in order to:

• look more like XPSP3/2k3sp2 taskmgr which has a smaller border there
• improve symmetry to the right border
• have more space for the actual listviews
• have slightly more space for the text of "Show processes from all users"

This requires moving both listviews and that Checkboxes x position slightly to the left.

when doing this remember to harmonize de-DE.rc text of IDS_MSG_TRAYICONCPUUSAGE

I will wait before starting to work on this until https://github.com/reactos/reactos/pull/4323 will be merged to avoid having that contributor to rebase anything.
