Remove Base.lib{blas,lapack}_name

[staticfloat]

These have been deprecated for a long time, users should instead use
LinearAlgebra.BLAS.libblas or LinearAlgebra.BLAS.liblapack.

This will be necessary once we have lazy JLLs, as it's not desirable to
recreate the dependency graph in Base, we already have it in standard
libraries, and only load libblastrampoline when LinearAlgebra starts
doing ccalls.

I think we definitely need to run PkgEval on this, to find more examples such as: JuliaLinearAlgebra/BandedMatrices.jl#386

I believe the decision from the last time was that removing these caused a lot of breakage. It does seem that most packages have been updated to avoid using the old names.

Are we good to merge this now?

[staticfloat]

Let's run PkgEval on it, just to see if the breakage is contained enough now.

The package evaluation job you requested has completed - possible new issues were detected.
The full report is available.

Looks like 70 odd packages still have libblas_name or liblapack_name. Maybe we need a call to action on Discourse with a list of these packages.

It turns out that almost all of them are all due to NNlib.

PR checklist:

• Transition to LinearAlgebra.BLAS.libblastrampoline instead of Base.libblas_name FluxML/NNlib.jl#589
• Transition to LinearAlgebra.BLAS.libblastrampoline instead of Base.liblapack_name JuliaGNSS/KalmanFilters.jl#14
