Make DimensionMismatch error string lazy (#34)

* Make `DimensionMismatch` error string lazy

This appeases `JET.jl` and makes this path testable for trimming with JuliaC.jl.

* Bump version

* Fixup lazy string for older Julia versions

This is fine since trimmability is anyways only a concern for later
versions of Julia.

* Update src/StaticArraysCore.jl
