We didn't set File line on ValueDeclr ImportDecl, TypeDecl

[omarsy]

Description:

The following code snippet produces an error in Gnolang, but the error message is misleading and does not point to the correct line number.

Code to Reproduce:

package main

func main() {
  var a, b, c = 1, 2
}

Expected Behavior:

The code should either compile correctly or produce a clear error message indicating the exact issue and the correct line number.

Actual Behavior:

The code returns the following error:

panic: main//src/package.gno:3: should not happen

The part "main//src/package.gno:3:" is not accurate because it does not set the line number of the ValuDelr type correctly. Instead, it takes the line number of the blocknode, which is misleading.
