[Buildroot] [PATCH v2 1/3] meson: new package

[Jörg Krause]

From: Eric Le Bihan <eric.le.bihan.dev at free.fr>

This new package provides the host variant of the Meson Build System, an
open source build system meant to be both extremely fast, and as user
friendly as possible.

More precisely, Meson creates configuration files for the Ninja build
system.

Besides building Meson, it generates a configuration file
("$(HOST_DIR)/etc/meson/cross-compilation.conf") to be used when
cross-compiling a Meson-based project.

Signed-off-by: Eric Le Bihan <eric.le.bihan.dev at free.fr>
[Jörg Krause:
 * bump to version 0.41.2
 * use explicit tarball release instead of github helper
 * use explicit sed
 * pass BR2_GCC_TARGET_CPU to cross file]
