Now that we have multi-stage bootstrapping, we can make the primary
builder build more dynamic. Add the concept of plugins that will be
linked and loaded into bootstrap_go_binary or bootstrap_go_package
modules. It's expected that the plugin's init() functions will do
whatever registration is necessary.
Example Blueprint definition:
bootstrap_go_binary {
name: "builder",
...
}
bootstrap_go_package {
name: "plugin1",
pluginFor: ["builder"],
}
A package may specify more than one plugin if it will be inserted into
more than one go module.

AddVariationDependencies is used to add dependency modules that
have the same variations as the depending module, but with additional
variataions. It cannot be used to add a dependency that is unrelated
to the depending module, for example a dependency on a code generator
that needs to run on the host to generate a target source file.
Add AddFarVariationDependencies, which adds a dependency on a module
that contains all the passed variations, but ignores the variations
of the depending module, as well as any unspecified variations on
the dependency module.

"Variant" has been used to mean two slightly concepts in Blueprint.
The first and most obvious is a variant of a module, meaning a list
of all the ways that on version of a module differs from other
versions of the same modules, for example "arch:arm, link:static".
The other is for the specific way that a version of a module differs,
"arch:arm".
Rename all of uses of "variant" as the second meaning to "variation",
and update the documentation to clarify "variant" vs. "variation".
This modifies the build logic api to convert CreateVariants to
CreateVariations.

The mutators that run after dependencies are resolved can be too late
to support build logic that needs to vary the dependencies based on
the mutated axis, for example architecture. This patch provides an
EarlyMutator interface that can be used to mutate modules before
any dependencies have been resolved.
In order for dependencies to be satisifed in a later pass, all
dependencies of a module must either have an identical variant,
must have a single variant, or must be inserted using
DynamicDependencyModuleContext.AddVariantDependency.

Replace the array of mutator name/variant name pairs with
a map of mutator name to variant name, and store the string
variant name separately.

Move most of the contents of moduleGroup into moduleInfo. This will
eventually reduce moduleGroup to a simple list of variants of the
same module.

Make integrating with go tools easier by putting the blueprint package
files in the top level directory of the git project instead of in a
subdirectory called blueprint.
