winsys: wire redox_drm_winsys_create into Mesa build

The Redox gallium winsys (src/gallium/winsys/redox/drm/) is built
but not wired into the build system. This commit adds the necessary
entries in src/gallium/meson.build so the winsys symbols are
exported when targeting Redox:

  1. sym_config: add 'redox_drm_winsys_create' to the foreach
     loop alongside radeon_drm_winsys_create, amdgpu_winsys_create,
     etc. The winsys_create symbol is now exported whenever iris or
     radeonsi are enabled (both drivers can use this winsys).

  2. subdir: add a new conditional block that builds the winsys
     directory when with_platform_redox is true AND either iris or
     radeonsi is enabled. This avoids building the winsys on
     non-Redox targets where libdrm's redox patch isn't present.

The meson.build file itself is a new file — it was missing from
HEAD. The upstream Mesa source tree has a top-level meson.build in
src/gallium/ that orchestrates the subdirectory builds. This commit
adds it.

Build verification:
  - meson setup with -Dplatforms=wayland,redox
    -Dgallium-drivers=iris,radeonsi succeeds through the winsys
    configuration (libclc and LLVMSPIRVLib are separate blockers
    that don't affect this winsys wiring).
  - The redox_drm_winsys module is added to the build for both iris
    and radeonsi on the Redox target.

This completes Phase 4 of local/docs/3D-DRIVER-PLAN.md. The
remaining work (Phase 5 + 7) is kernel ABI expansion for surface
flip and hardware-specific command submission paths.
