[COMMON] [R] Migrate to display stack at CAF 9.1[25] branches/tags

[MarijnS95]

Notable changes include:

• Finally! Vintf fragments! Now we don't need to keep track of these ourselves anymore, the module itself automatically supplies them to the build system;
• Composer is now its own executable HAL, instead of a libhardware module loaded by a passthrough (AOSP) service;
• Blobs link against QTI mapper@2.0; EGL fails to probe without it.

We cannot merge this before knowing the impact on other platforms! As usual the HAL might run on 4.14 devices, but more than likely it does not. Tough luck, we'll need to come up with guards around all these changes.

No you cannot get the new HALs on the 4.14 BSPs, you will get incompatibilities with the proprietary sdmextension.

Add the proper barriers for the 4.19 based projects and #shipit
