This effectively moves execution of Bazel actions outside of soong_build
and alongside ninja execution of the actual ninja files, whether that be
by ninja or by Bazel itself.
This almost allows for mixed builds and Bazel-as-Ninja-executor to
coexist, but requires hacks explained in b/175307058.
Test: Treehugger
Test: lunch aosp_flame && USE_BAZEL_ANALYSIS=1 m libc
Test: lunch aosp_flame && USE_BAZEL=1 USE_BAZEL_ANALYSIS=1 m libc,
though this requires a hack of the main BUILD file. See b/175307058

Bazel is executed several times during the execution of soong_build.
For each bazel execution, generate a profile and save under the
BAZEL_METRICS_DIR which is defined in soong_ui.
Bug: b/174479924
Test: * USE_BAZEL_ANALYSIS=1 USE_BAZEL=1 m nothing and checked
if the cquery and graph build bazel profiles were generated.
* Verified that the generated bazel profiles were uploaded
to the local dev metrics pipeline.

This removes the need to source bazelenv.sh for USE_BAZEL_ANALYSIS, and
unifies mixed builds to use the checked in tools/bazel and bazelrc.
It also unifies all bazel-related output to be in out/bazel.
Without aosp/1502095, this change still requires toplevel_output_directories to be an empty
list, otherwise there'll be this error:
ERROR: Directories specified with toplevel_output_directories should be
ignored and can not be used as sources.
Test: With aosp/1441774: rm -rf out/ && lunch aosp_cf_x86_auto && USE_BAZEL_ANALYSIS=1 m libc && prebuilts/build-tools/linux-x86/bin/ninja -f out/combined-aosp_cf_x86_auto.ninja -t commands libc | grep bazel-out | wc -l # 2 results

As a result, one can enable bazel-as-ninja-executor separately from
mixed builds.
Test: Manually verified building image with and without bazelenv.sh.

With this change, bazel_module is a specifiable property on
genrule module definitions. With bazel-enabled mode, soong_build will
defer to Bazel for information on these modules.
source build/soong/bazelenv.sh to enter bazel-enabled mode.
Test: Manually verified on bionic/libc genrules using aosp_cf_x86_phone-userdebug
