* fix(ci): fix AMDGPU_TARGETS empty-string bypass in hipblas builds
399c1dec wired amdgpu-targets through the backend_build workflow_call
interface, intending the input's default value to cover matrix entries
that don't specify targets. However, GitHub Actions only applies a
workflow_call input default when the caller omits the input entirely.
When backend.yml passes `amdgpu-targets: ${{ matrix.amdgpu-targets }}`
and the matrix entry has no amdgpu-targets key, the expression evaluates
to an empty string, which is treated as an explicit value — bypassing
the default. The result is Docker receiving AMDGPU_TARGETS="" which in
turn causes Make's ?= default to be skipped (since the variable is
already set in the environment, even to empty), and cmake gets
-DAMDGPU_TARGETS= with no targets, so the HIP backend compiles for an
indeterminate target rather than the intended GPU list.
Fix this at two levels:
1. backend.yml: use a || fallback in the expression so that an undefined
matrix.amdgpu-targets never reaches the reusable workflow as an empty
string. The target list is the canonical default and lives here.
2. backend_build.yml: remove the now-misleading default value from the
input declaration. The default never fired due to the above bug, so
keeping it implied a guarantee that didn't exist.
3. backend/cpp/llama-cpp/Makefile: add an explicit $(error ...) guard
after the ?= assignment so that if AMDGPU_TARGETS is empty (whether
from environment or any future CI wiring mistake) the build fails
immediately with a clear message rather than silently producing a
binary compiled for an unknown GPU target.

* fix(build): plumb AMDGPU_TARGETS through to Docker builds
The docker-build-backend Makefile macro and Dockerfile.golang did not
pass AMDGPU_TARGETS to the inner make invocation, so hipblas builds
always used the backend Makefile's hardcoded default GPU targets
regardless of what was specified via environment or CI inputs.
