[CI] (.github/workflows, scripts/ci): configure both Linux builds from one script

Browse Source 
- scripts/ci/configure_build.sh holds build-linux's (primary) and build-linux-split's (split) configure lines, flag for flag as before
- scripts/ci/build_fingerprint.py compares two configured trees (cache, compile commands, link statements, CTest files, toolchain) with the build path normalised and the benchmarks left out; its guard configures a probe through the script and never counts thin evidence as equal
- pipe-gates runs its self-test; no job uses the guard yet

"""Prove that two CMake build trees were configured identically, apart from the benchmarks.
build-linux and build-linux-split configure the same sources twice. On the disaggregation
branches the only intended difference is MOBILEGL_BUILD_BENCHMARK, which adds MG_Benchmark and the
google benchmark dependency and touches nothing else. When the two configurations are equal, the
split consumers can take build-linux's artifacts and build-linux-split need not compile again.
The fingerprint is read from what configure writes, so it can be taken before the build:
cache MOBILEGL_* entries (except MOBILEGL_BUILD_BENCHMARK), the build type, compilers,
launchers, flags and the link tools from CMakeCache.txt;
compile every compile_commands.json entry: file, output and arguments;
link every link statement of build.ninja: outputs, rule, inputs and variables;
tests the text of every CTestTestfile.cmake and gtest *_include.cmake;
toolchain compiler, linker, cmake, ninja and package versions on this runner;
image the runner image, recorded and never compared.
The build directory's own path is replaced by @BUILD@, and everything under MobileGL/MG_Benchmark
or the benchmark dependency is left out. A fingerprint with fewer than 200 compile entries, 3 link
statements (libMobileGL.so among them) or 2 CTest files proves nothing and never counts as equal.
build_fingerprint.py fingerprint --build-dir D [--out F]
build_fingerprint.py compare A.json B.json
build_fingerprint.py guard --built D --probe primary|split --probe-dir P [--github-output KEY]
build_fingerprint.py --self-test
guard configures the probe with scripts/ci/configure_build.sh (configure only), compares it with
the built tree and writes KEY=true|false to $GITHUB_OUTPUT. Any error makes it false, and it always
exits 0: a difference sends the workflow down the path that builds both, it is not a red.

# The configure lines of the two Linux library builds, in one place, so build-linux and
# build-linux-split run exactly these and build_fingerprint.py can configure either one as a probe.
# primary build-linux's: CI_BUILD_TYPE (default Release), MOBILEGL_CI_DISAGGREGATED (ON or OFF,
# required) for the transport, the benchmarks, compile_commands.json.
# split build-linux-split's: Release, the transport and its in-process arm always on.
# Both default to Release at the INFO log level, like the shipped build. INFO is load-bearing: the
# library logs the resolved transport at INFO, and run_trace_case.cmake and the split lanes read
# that line back as proof the transport resolved in the process under test.
#
# usage: configure_build.sh <primary|split> <build dir>
# with MOBILEGL_CI_CC, MOBILEGL_CI_CXX and VK_ICD_FILENAMES from setup-test-runner.
