fix(enclave): remove build.rs and copy data files

[hu55a1n1]

We hit a build issue in #258 when depending on quartz-enclave-core v0.1.0 ->

cycles-quartz/examples/transfers/enclave$ cargo build
   Compiling quartz-proto v0.1.0
   Compiling quartz-contract-core v0.1.0
   Compiling quartz-tm-stateless-verifier v0.1.0
   Compiling quartz-enclave-core v0.1.0
   Compiling quartz-tm-prover v0.1.0
   Compiling cw-client v0.1.0
error: failed to run custom build command for `quartz-enclave-core v0.1.0`

Caused by:
  process didn't exit successfully: `/home/vboxuser/Downloads/cycles-quartz/examples/transfers/target/debug/build/quartz-enclave-core-e346fbb3e8b55026/build-script-build` (exit status: 101)

This is basically caused due to a bug in the build.rs script's handling of paths. This PR removes the build.rs script entirely and jsut copies the DCAP certs/files into the crate. The PR also bumps the version of the quartz-enclave-core and quartz-common crates to v0.1.1.
