libqmi: switch to meson build tools

libqmi: switch to meson build tools

Using https://gitlab.freedesktop.org/mobile-broadband/libqmi.git to download the source code.
Enabled lto and additional gcc flags for perfomance and less size.
Added support for selecting qmi message collection.
Selected basic qmi message collection by default (modemmanager requires it).
Modified to use meson as upstream has abandoned autotools.
Removed BUILD_PARALLEL options. These are default with ninja/meson.
