gfxstream: meson qnx cross build
Pkgconfig wasn't able to resolve the dependencies for qnx build, so the
libraries and headers are found and added manually. Hopefully we can get
pkgconfig working soon to clean this up.
A `qnx` directory is added to the project root for qnx build scripts and
cross files. A script also handles the aemu dependency. Run 'make' to
build cross-compiled aemu deps, and then gfxstream. Cmake toolchain
file is added for building the aemu dependancy.
BUG=287082350
TEST=qnx cross compile: cd qnx || make

+# Build: QNX
+
+Requires QNX SDP to build, with `QNX_TARGET` and `QNX_HOST` environment variables set. Make sure the latest meson is installed.
+
+Build scripts are made available to show how to cross-compile gfxstream and its aemu dependencies. See `./qnx/nto/build-aemu.sh` and `./qnx/nto/build-gfxstream.sh`
+
+ cd ./qnx
+ make
+
+Make will navigate to `./qnx/nto/aarch64le` and run the build scripts from there.
+
+The aemu dependency is downloaded to, and built in `./qnx/nto/aarch64le/aemu`.
+
+Gfxstream's build directory is `./qnx/nto/aarch64le/gfxstream`.
+
+ cd ./qnx
+ make install
+
+The install target requires the `INSTALL_ROOT_nto` environment variable, which sets the qnx staging/install path.
+
+pinfo.mk writes build info into the binary:
+
+ # use -i ./nto/aarch64le/gfxstream/host/libgfxstream_backend.so
+ QNX_BUILDID=(GNU)5dc1327b962ed2a7e992c1f6f35c0df3
+ NAME=libgfxstream_backend.so
+ DESCRIPTION=virtio-gpu backend renderer
+ DATE=2023/09/18-10:58:49-EDT
+ COMMIT=7b8c19e51845aee014684c43e6aa8409e919af6a
+
+A "recursive make" directory layout is used to allow multiplatform builds. For more info, see: [Conventions for Recursive Makefiles and Directories](https://www.qnx.com/developers/docs/7.1/#com.qnx.doc.neutrino.prog/topic/make_convent.html)
