Add minimize command

[Jake-Shadle]

This PR adds a minimize subcommand that performs a splat, followed by running an actual compile for windows (defaults to x86_64-pc-windows-msvc) wrapped in strace so that xwin can detect all file accesses to headers and libraries in the crt and sdk, and writing only those accessed files to a map file. This map file can then be used with a splat to only splat and symlink the files listed in map file.

This results in a vastly smaller splat output eg. from 577 MiB -> 105 MiB for a large internal project that includes a significant amount of C/C++ code.

This also adds a --sdk-version and --crt-version so allow users to explicitly specify the sdk/crt to use, rather than the default behavior of always using the latest version detected in the manifest used. This was primarily done due to some CRT in the latest version required clang 16+, from the previous lowest version being 11, which can be too much of a jump for some people.

Nice! Don't forget to add it (and the new version flags) to the README though 😬
