Subject: round-robin-bisect.sh: Allow passing parameters to the baseline build

... which enabled bisects for configurations with no branches/entries
in base-artifacts.git repo.  This allows for testing, analysis and
investigation of CI projects/configurations that are in early
development.

E.g., to bisect LLVM revisions between reelease/13.x and release/14.x
for a tcwg_aosp_size project with no entries in base-artifacts.git
one could use:
~/jenkins-scripts/round-robin-bisect.sh %%rel_artifacts artifacts-1 \
 --current_project llvm \
 --bad_git https://github.com/llvm/llvm-project.git#release/14.x \
 --build_script ~/jenkins-scripts/tcwg_aosp-build.sh \
 -- \ # start of usual bisect parameters
 ==rr[ci_project] "tcwg_aosp_size" \
 ==rr[ci_config] "llvm-release-aarch64-aosp-release" \
 -- \ # start of parameters for the baseline build
 ==rr[llvm_git] "https://github.com/llvm/llvm-project.git#release/13.x" \
 ==rr[aosp-manifest_git] "https://android.googlesource.com/platform/manifest.git#a7b08be17efeef04c2eb647caf3c180a539058cf" \
 ==rr[toolchain-manifest_git] "https://android.googlesource.com/platform/manifest.git#13eb2b0abf6258f076eb41d590fc71396186eae7"
