Add AtomicMemorySentinel for cross-platform atomic
memory synchronization. This provides a
platform-agnostic API over Linux futex syscalls,
allowing shared memory synchronization via
memory-mapped file descriptors.
Includes Linux futex implementation and stub
implementations for Windows and other platforms.

On v14+, flat source formats are no longer supported by LD_VAR_BUF and
LD_VAR_BUF_IMM opcodes. This patch makes the compiler emit the
dedicated LD_VAR_BUF_FLAT* opcodes instead.
Add the ISA definitions, handle the new opcodes, and add packing tests
for both immediate and indirect forms.

The provoking vertex bit in RUN_FRAGMENT2 is located in a register
instead of a descriptor stored in memory. That means we don't need to
patch memory, resulting in a much leaner implementation compared to
RUN_FRAGMENT.
Also, implement the simultaneous reuse copy path with the corresponding
tiler pointer patching.

Commit 718ef151f2 removed the legacy non-dmabuf wl_drm path and now
gates the extension on has_dmabuf_import && has_dmabuf_export. These
flags reflect driver capability and do not depend on whether a valid DRM
render fd was assigned during display initialization.
Before commit 718ef151f2, dri2_get_capabilities() returned 0 for
kms_swrast paths because can_share_buffer is false there, so the
__DRI_IMAGE_CAP_GLOBAL_NAMES check naturally excluded software-only
devices. The replacement dmabuf flags do not have this property.
On a software-only device (e.g., vgem), fd_render_gpu stays -1 and
device_name is NULL, yet both dmabuf flags are true, causing the
extension to be incorrectly advertised. When a Wayland compositor calls
eglBindWaylandDisplayWL(), drmGetRenderDeviceNameFromFd(-1) returns NULL
and strdup(device_name) is called on a NULL pointer, causing a SIGSEGV.
Add an additional guard when setting WL_bind_wayland_display,
so the extension is only advertised when a valid DRM render fd is present
