Remove lto from the release profile

The performance difference has shrunk substantially adding inline to a
bunch of functions. The performance difference with or without lto is
about 4 seconds on the slowest clip/qp on a standard awcy run
(MINECRAFT, objective-1-fast, qp 80). The compile time difference is 42
seconds.

If it's possible to have good performance with lto off, then optimizing
without it will provide a good development profile. Going forward, it
would be advisable to use lto to check for performancem problems. It
may be possible to create a seperate profile between dev and release.
Would require rust-lang/cargo#6988 and AWCY
would need to be modified to use the new profile/still work with old
versions of rav1e.
