tpm: Add tpm2-sys crate This CL adds a tpm2-sys crate that builds libtpm2 from source (from a git submodule) using the existing Makefile and then links the generated static library as -ltpm2. For production builds there is a flag `RUSTFLAGS='--cfg hermetic'` to disallow building our own libtpm2. Instead it will expect to find libtpm2 installed in the standard system location. Building from the libtpm2 submodule is a convenience only intended for developer environments. The functions exposed by tpm2-sys are the ones that will be necessary to initialize a TPM simulator in crosvm and execute TPM commands. Trunks uses the same functions for its simulator mode here: https://chromium.googlesource.com/chromiumos/platform2/+/e4cf13c05773f3446bd76a13c4e37f0b80728711/trunks/tpm_simulator_handle.cc Tested by running: fn main() { unsafe { tpm2_sys::TPM_Manufacture(1); } } inside cros_sdk. Libtpm2 cannot be built outside of cros_sdk because it requires openssl 1.0.2p, whereas dev machines come with openssl 1.1.0j. I have not yet added any dependency on tpm2-sys from crosvm, but when it does get added it will be behind a tpm feature flag so that crosvm can continue to build outside of cros_sdk just without tpm support. I published num_cpus version 1.9.0 to chromeos-localmirror.

Update tpm2-sys build.rs to support cross-compilation Also removes the use of the hermetic flag in favor of not failing the build if the submodule is not checked out. This allows us to remove the tpm2 build from the build_environment Makefile.
