Sergey Dmitriev b305d26b57 [OpenMP] libomptarget: move debugging dumps under control of env var LIBOMPTARGET_DEBUG 
Disable default debugging dumps for libomptarget and plugins and move dumps
under control of environment variable LIBOMPTARGET_DEBUG=<integer>. Dumps
are enabled when LIBOMPTARGET_DEBUG is set to a positive integer value.

Debugging dumps are available only in debug build; release build does not
support it.

George Rokos 1546d31924 [OpenMP] Changes in the plugin interface 
This patch chagnes the plugin interface so that:
1) future plugins can take advantage of systems with shared CPU/device storage
2) instead of using base addresses, target regions are launched by providing target addresseds and base offsets explicitly.
