Delete support for standalone Blueprint.

Now that Blueprint has been merged with Soong, a large amount of code is
unnecessary.

Test: Presubmits.

#
# It can also be invoked from another script to bootstrap a custom Blueprint-

# WRAPPER
# SRCDIR

// The Blueprint bootstrapping mechanism is intended to enable building a
// source tree with minimal prebuilts. The only prerequisites for performing
// such a build are:
//
// 1. A Ninja binary
// 2. A script interpreter (e.g. Bash or Python)
// 3. A Go toolchain
//
// The Primary Builder
//
// As part of the bootstrapping process, a binary called the "primary builder"
// is created. This primary builder is the binary that includes both the core
// Blueprint library and the build logic specific to the source tree. It is
// used to generate the Ninja file that describes how to build the entire source
// tree.
//
// The primary builder must be a pure Go (i.e. no cgo) module built with the
// module type 'bootstrap_go_binary'. It should have the 'primaryBuilder'
// module property set to true in its Blueprints file. If more than one module
// sets primaryBuilder to true the build will fail.
//
// The primary builder main function should look something like:
//
// package main
//
// import (
// "flag"
// "github.com/google/blueprint"
// "github.com/google/blueprint/bootstrap"
// "path/filepath"
//
// "my/custom/build/logic"
// )
//
// func main() {
// // The primary builder should use the global flag set because the
// // bootstrap package registers its own flags there.
// flag.Parse()
//
// // The top-level Blueprints file is passed as the first argument.
// srcDir := filepath.Dir(flag.Arg(0))
//
// // Create the build context.
// ctx := blueprint.NewContext()
//
// // Register custom module types
// ctx.RegisterModuleType("foo", logic.FooModule)
// ctx.RegisterModuleType("bar", logic.BarModule)
//
// // Register custom singletons
// ctx.RegisterSingleton("baz", logic.NewBazSingleton())
//
// // Create and initialize the custom Config object.
// config := logic.NewConfig(srcDir)
//
// // This call never returns
// bootstrap.Main(ctx, config)
// }
//
// Required Source Files
//
// There are three files that must be included in the source tree to facilitate
// the build bootstrapping:
//
// 1. The top-level Blueprints file
// 2. The bootstrap script
// 3. The build wrapper script
//
// The top-level Blueprints file describes how the entire source tree should be
// built. It must have a 'subdirs' assignment that includes both the core
// Blueprint library and the custom build logic for the source tree. It should
// also include (either directly or through a subdirs entry) describe all the
// modules to be built in the source tree.
//
// The bootstrap script is a small script to setup the build directory, writing
// a couple configuration files (including the path the source directory,
// information about the Go build environment, etc), then copying the build
// wrapper into the build directory.
//
// The Bootstrapping Process
//
// There are three stages to the bootstrapping process, each with a
// corresponding Ninja file. The stages are referred to as the "bootstrap",
// "primary", and "main" stages. Each stage builds the next stage's Ninja file.
//
// The bootstrapping process begins with the user running the bootstrap script
// to initialize a new build directory. The script is run from the build
// directory, and creates a ".minibootstrap/build.ninja" file that sets a few
// variables then includes blueprint's "bootstrap/build.ninja". It also writes
// out a ".blueprint.bootstrap" file that contains a few variables for later use:
//
// BLUEPRINT_BOOTSTRAP_VERSION - Used to detect when a user needs to run
// bootstrap.bash again
//
// SRCDIR - The path to the source directory
// BLUEPRINTDIR - The path to the blueprints directory (includes $SRCDIR)
// GOROOT - The path to the root directory of the Go toolchain
// NINJA_BUILDDIR - The path to store .ninja_log, .ninja_deps
//
// Once the script completes the build directory is initialized and ready to run
// a build. A wrapper script (blueprint.bash by default) has been installed in
// order to run a build. It iterates through the three stages of the build:
//
// - Runs microfactory.bash to build minibp
// - Runs the .minibootstrap/build.ninja to build .bootstrap/build.ninja
// - Runs .bootstrap/build.ninja to build and run the primary builder
// - Runs build.ninja to build your code
//
// Microfactory takes care of building an up to date version of `minibp` and
// `bpglob` under the .minibootstrap/ directory.
//
// During <builddir>/.minibootstrap/build.ninja, the following actions are
// taken, if necessary:
//
// - Run minibp to generate .bootstrap/build.ninja (Primary stage)
// - Includes .minibootstrap/build-globs.ninja, which defines rules to
// run bpglob during incremental builds. These outputs are listed in
// the dependency file output by minibp.
//
// During the <builddir>/.bootstrap/build.ninja, the following actions are
// taken, if necessary:
//
// - Build the primary builder, anything marked `default: true`, and
// any dependencies.
// - Run the primary builder to generate build.ninja
// - Run the primary builder to extract documentation
// - Includes .bootstrap/build-globs.ninja, which defines rules to run
// bpglob during incremental builds. These outputs are listed in the
// dependency file output by the primary builder.
//
// Then the main stage is at <builddir>/build.ninja, and will contain all the
// rules generated by the primary builder. In addition, the bootstrap code
// adds a phony rule "blueprint_tools" that depends on all blueprint_go_binary
// rules (bpfmt, bpmodify, etc).
