This commits moves all `.d.ts` files from `ext/*` to `cli/tsc/dts`. Due to TSC snapshot removal, `cargo publish` is now erroring out, unable to find the declaration files. These files were moved to "cli/tsc/dts", because it's much easier than keeping them in extension directories, while still providing them compressed or uncompressed depending on the build type.
