fix(compile): don't surface graph errors for --include files (#34568)

Files passed to deno compile via --include were added as module graph
roots, so when an embedded JS, Wasm or JSON asset contained an unresolvable import
(for example a pre-bundled file, or a wasm module with host imports) the
whole compilation failed with a graph resolution error, or a type error when
type checking was on, instead of just embedding the file. This was a
regression from 2.2.6 and made it impossible to embed bundled frontend assets or certain
wasm files.

This separates the strict graph roots (the entrypoint plus any --preload
and --require modules) from the --include module roots. Only the strict
roots are validated and type checked, so real errors in the user's program are
still reported. The stored module graph is then built from all roots with
create_graph, which does not validate, so included files are still
transpiled and embedded but their own graph resolution errors no longer fail the
build. A consequence is that --include files are treated as best effort assets
and are no longer type checked.
