Enhance Upload Firrtl Binaries (#4887)

* Change Upload Binaries to Upload Firrtl Binaries

This vastly reduces the size of the uploaded binaries while still
serving the needs of Firrtl users.

* Don't build tools when building LLVM

They are not part of the binary release and are unnecessary for building
CIRCT.

* Use CIRCT_RELEASE_TAG=firtool

This works for both tagged releases and will give a version derived from
`git describe --tags` when building from non-tagged commits.
