meta-xilinx: Clean up vendor specific machine configuration files

1. Add new metal-xilinx-vendor layer which supports vendor specific
   machine configuration files, device-tree, kernel, platform-init etc.
2. Moved below vendor machine conf files, dt and related configs from
   meta-xilinx-bsp and meta-xilinx-contrib to meta-xilinx-vendor layer.
    - microzed-zynq7.conf
    - minized-zynq7.conf
    - picozed-zynq7.conf
    - zedboard-zynq7.conf
    - zybo-zynq7.conf
    - zybo-linux-bd-zynq7.conf
    - ultra96-zynqmp.conf
3. Obsolete qemu-zynq7, s3adsp1800-qemu-microblazeeb, v350-versal and
   vc-p-a2197-00-versal from meta-xilinx-bsp layer. Users should use
   zynq-generic.conf for zynq7000 qemu boot should be functionally
   equivalent to qemu-zynq7.
4. Add new MAINTAINERS.md file and move maintainers, Mailing list and
   Patches content from meta-xilinx-* README.md to MAINTAINERS.md file.
5. Updated README.md file for supported board machines files in
   meta-xilinx-bsp, meta-xilinx-contrib and meta-xilinx-vendor layers.
6. Disabled old drm kernel patches for zybo-linux-bd-zynq mahcine in
   meta-xilinx-contrib layer as these patches doesn't apply on 5.x
   kernel, if we don't hear from patch submitter we will remove these
   patches from meta-xilinx-contrib layer.
7. Removed drm kernel cache metadate for zybo-linux-bd-zynq7 machine
   as these configs are already available in xilinx_zynq_defconfig.
8. Fixed build issue for u-boot by changing
   PREFERRED_PROVIDER_virtual/bootloader from u-boot to u-boot-xlnx.
9. Add meta-xilinx-vendor to bblayers.conf.sample
