Include Windows .asm source files in packaged releases.

Pregenerate .asm files to pregenerated/ instead of pregenerated/tmp.

This simplifies the future prepackaging the symbol prefixing headers
for cargo-vendor users.

This also makes progress towards allowing users of `cargo vendor` to
eventually assemble the assembly sources on Windows themselves if they
prefer.
