Rust Code Coverage Reporting (filecoin-project#612)

* first stab at CI

* dont use cuda for CI, enable debug feature for SDK

* merge coverage action with main ci test run

* add special case for matrix item

* rename uses to tool to avoid keyword conflict

* just download llvm-cov for every item in matrix for now

* if statement test

* fix ci if statements (hopefully)

* maybe fix if statement

* fix ci if statements for sure this time

* use sha hash for ci dep versions, dont import llvm-cov when uneeded

* split integration tests into its own job for seperate coverage tooling later, use version number for instead of sha for sub-tool

* add right tools to test job

* fix coverage report file output names

* rename jobs
