package/mesa3d: switch build system to meson

Update patches for meson:
0002-configure.ac-invert-order-for-wayland-scanner-check.patch
0003-set-LIBCLC_INCLUDEDIR.patch

Disable unused options that are set to "auto" mode.
(valgrind, gallium-omx, power8).

Remove --disable-static option since there is no meson equivalent.
Remove --disable-mangling since it's not yet supported by meson.

Use r100 instead of radeon as DRI name for BR2_PACKAGE_MESA3D_DRI_DRIVER_RADEON.

Add a new depedency on host-python3-mako since we can't use
generated headers from the release archive [2].

+LIBCLC_INCLUDEDIR is the location where mesa3d OpenCL implementation

+The value returned by pkg-config for includedir is relevant when
