Previously, Configurable.Get() copied the value in the property,
because it needed to return a pointer in order to indicate whether
the property was set or not. Now, it returns a ConfigurableOptional[T],
which is the same as the pointer, but it prevents users from altering
the pointed-to value, so we don't need to copy it.
There are still copies for slice properties, because those are also
pointers. In the future we may want to consider making an ImmutableList
type to use instead.

Select statements are a new blueprint feature inspired by bazel's select
statements. They are essentially alternative syntax for soong config
variables that require less boilerplate. In addition, they support
making decisions based on a module's variant, which will eliminate
the need for manual property struct manipulation, such as the arch
mutator's arch: and target: properties.
In order to support decisions based on the variant, select statements
cannot be evaluated as soon as they're parsed. Instead, they must be
stored in the property struct unevaluated. This means that individual
properties need to change their type from say, string, to
Configurable[string]. Currently, only configurable strings, bools, and
string slices are supported, but more types can be added later.
The module implementation must call my_property.Evaluate(ctx) in order
to get the final, resolved value of the select statement.

When setProvider() is called, hash the provider and store the hash in
the module. Then after the build is done, hash all the providers again
and compare the hashes. It's an error if they don't match.
Also add a flag to control it in case this check gets slow as we convert
more things to providers. However right now it's fast (unnoticable
in terms of whole seconds) so just have the flag always enabled.

In conjunction with soong/build changes, this materialized runtime
metrics for various soong_build events.
Test: Manually verified materialized protos for bp2build, mixed builds,
and legacy build.

This was the only one in the source tree.
Side cleanup: remove some dead code that I assume comes from the time
where Blueprint files had to specify what subdirectories other Blueprint
files are in.
Test: Presubmits.
