Aligns version between `deno`, `denort` and `deno_lib` crates.
Removes `cli/lib/version.txt` and some build-script shenanigans to
override crate version.
This slightly degrades the performance of CJS export analysis on
subsequent runs because I changed it to no longer cache in the DENO_DIR
with this PR (denort now properly has no idea about the DENO_DIR). We'll
have to change it to embed this data in the binary and that will also
allow us to get rid of swc in denort (will do that in a follow-up PR).
