This PR allows to optionally speed up the lookup of symbols by providing a `SymbolTableCollection` instance to the interested conversion patterns. It is follow-up on the discussion about symbol / symbol table management carried on [Discourse](https://discourse.llvm.org/t/symbol-table-as-first-class-citizen-in-builders/86813).

These functions are called from lowering patterns. All IR modifications
in a pattern must be performed through the provided rewriter, but these
functions used to instantiate a new `OpBuilder`, bypassing the provided
rewriter.

On lowering from `memref` to LLVM, `malloc` and other intrinsic
functions from `libc` will be declared in the current module. User's
redefinition of these reserved functions will poison the internal
analysis with wrong prototype. This patch adds assertion on the found
function's type and reports if it mismatch with the intended type.

This commit removes the no longer required type pointer helpers from the
LLVM dialect conversion utils. Typed pointers have been deprecated for a
while now and it's planned to soon remove them from the LLVM dialect.

Printing strings within integration tests is currently quite annoyingly
verbose, and can't be tucked into shared helpers as the types depend on
the length of the string:

```
llvm.mlir.global internal constant @hello_world("Hello, World!\0")

func.func @entry() {
  %0 = llvm.mlir.addressof @hello_world : !llvm.ptr<array<14 x i8>>
  %1 = llvm.mlir.constant(0 : index) : i64
  %2 = llvm.getelementptr %0[%1, %1]
    : (!llvm.ptr<array<14 x i8>>, i64, i64) -> !llvm.ptr<i8>
  llvm.call @printCString(%2) : (!llvm.ptr<i8>) -> ()
  return
}
```

So this patch adds a simple extension to `vector.print` to simplify
this:
```
func.func @entry() {
   // Print a vector of characters ;)
   vector.print str "Hello, World!"
   return
}
```

Most of the logic for this is now shared with `cf.assert` which already
does something similar.

Depends on #68694
