Chris Parsons dbcb1ff469 Use aquery to declare bazel actions in the ninja file. 
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

Patrice Arruda 05ab2d0731 Enable bazel profiling in soong_build. 
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.

Jingwen Chen 30f5aaaa77 Move bazel_module property to a common file, and add it to filegroup. 
This enables prototyping against aosp/1441774 to demonstrate mixed
builds with converted BUILD files.

Test: TH Presubmit
Test: 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 build actions

Jingwen Chen 7c6089ad95 Integrate bazelenv.sh environment variables into soong_ui environment. 
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

Chris Parsons 8b77a009e2 Change mixed soong/bazel builds to use USE_BAZEL_ANALYSIS 
As a result, one can enable bazel-as-ninja-executor separately from
mixed builds.

Test: Manually verified building image with and without bazelenv.sh.

Chris Parsons f3c96efea4 Mixed bazel/soong build prototype for genrule 
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
