Rollup merge of #137505 - tgross35:builtins-cannot-call-error, r=compiler-errors 
Add a span to `CompilerBuiltinsCannotCall`

Currently, this error emit a diagnostic with no context like:

    error: `compiler_builtins` cannot call functions through upstream monomorphizations; encountered invalid call from `<math::libm::support::hex_float::Hexf<i32> as core::fmt::LowerHex>::fmt` to `core::fmt::num::<impl core::fmt::LowerHex for i32>::fmt`

With this change, it at least usually points to the problematic function:

    error: `compiler_builtins` cannot call functions through upstream monomorphizations; encountered invalid call from `<math::libm::support::hex_float::Hexf<i32> as core::fmt::LowerHex>::fmt` to `core::fmt::num::<impl core::fmt::LowerHex for i32>::fmt`
