deploy-sycl-toolchain build target missing L0 library dependencies

[EwanC]

Describe the bug

From testing the L0 loader bump PRs:

• [L0] Update Level Zero Loader version to v1.18.5 oneapi-src/unified-runtime#2279 / [UR][L0] Update Level Zero Loader version to v1.18.5 #15967
• [SYCL][Graph] Only get command handle for updatable command-buffers #15522 (comment)

I have discovered that the deploy-sycl-toolchain build target does not include all the necessary L0 dependencies.

To reproduce

With git branch from #15967

$ python3 buildbot/configure.py
$ python3 buildbot/compile.py
$ cd build
$ ./bin/sycl-ls
SYCL Exception encountered: Native API failed. Native API returns: 2147483646 (UR_RESULT_ERROR_UNKNOWN)
$ ninja deploy-sycl-toolchain
$ ./bin/sycl-ls
SYCL Exception encountered: Native API failed. Native API returns: 2147483646 (UR_RESULT_ERROR_UNKNOWN)
$  ninja libze_tracing_layer.so
$ ./bin/sycl-ls
<works correctly>

In this case manually building libze_tracing_layer.so fixes the issue, however I am not knowledgeable about DPC++ CMake or L0 to know if this is the only missing dependency.

EDIT On another system I also had to manually build the ninja libze_validation_layer.so target
