[PATCH 3/9] devtool: ide-sdk: pre-select attach process with processFilter

[AdrianF <adrian.freihofer@siemens.com>]

From: Adrian Freihofer <adrian.freihofer@siemens.com>

The ATTACH launch config now uses the extended-remote protocol, which
makes cppdbg show a picker listing every process running on the
target. In modified-recipe mode the binary to attach to is already
known, so the picker is only extra clicking, and on a busy target it
can make finding the right process among unrelated ones tedious.

Set "processFilter" to a regex matching the deployed binary's path so
cppdbg pre-selects it instead of showing the full process list. This
is a recent cpptools feature; until it ships in a released cpptools,
cppdbg silently ignores it and falls back to showing the full
unfiltered process list.

Require cpptools version that supports processFilter
