meson: build libnvme directly instead of as a subproject

Change the build flow so that libnvme is no longer defined as a Meson
subproject of nvme-cli. Instead, include libnvme's meson.build directly
from the top-level meson.build.

This allows sharing a common ccan directory between nvme-cli and libnvme,
and generates a single configuration header, project-config.h (formerly
config.h), used by all components. The old file name conflicted with
plugins/solidigm/solidigm-telemetry/config.h, hence the rename.

Also reformat all meson.build files to fix indentation inconsistencies and
other cosmetic discrepancies.
