This changes the syntax from select(variant("arch"), {...}) to
select(arch(), {...}) to make it shorter and to make it clear that
we can restrict what variants you can select on.

Also added tests for both multivariable and typed selects.

Part of the design of property structs is that they were easy to access.
In keeping with that spirit, use a shorter and easier to spell name
for the getter, and add GetDefault() so that you don't need to pass
the result of Get() to one of the
proptools.StringDefault/BoolDefault/etc functions.

Previously I was using an underscore to denote the default branch
because I was thinking that I would allow variable bindings in the
select branches, and 'default' could be mistaken for the name of a
variable. But I think it's better to just introduce alternate syntax,
like `default @ my_var: "foo" + my_var,` to do the variable bindings,
so that we can have a clearer name for the default case.

Things still to do:
- Support selecting on product variables and
variants
- Test/Support property struct reflection tags
like arch_variant, path, and variant_prepend
- Test that selects combine well with existing
configurability mechanisms like arch:, target:,
multilib:, python's version:, etc.
