fix(acvm): Clear ACIR call stack after successful circuit execution (#5783)

# Description

## Problem\*

Resolves <!-- Link to GitHub Issue -->

No issue as small issue found while working on bug related to brillig.

## Summary\*

Changing `fold_nested_brillig_assert_fail` to the following main (where
we expect the second call to fail):
```rust
fn main(x: Field) {
    assert(1 == fold_conditional_wrapper(!x as bool));
    assert(1 == fold_conditional_wrapper(x as bool));
}
```
would lead to this call stack:
```
error: Failed to solve program: 'Failed to solve brillig function'
   ┌─ /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:27:12
   │
27 │     assert(x);
   │            -
   │
   = Call stack:
     1. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:6:17
     2. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:12:5
     3. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:7:17
     4. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:12:5
     5. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:18:9
     6. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:23:5
     7. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:27:12
```
These lines should not be included and reference the successful call
before the second one:
```
     1. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:6:17
     2. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:12:5
```
The following change now has the correct call stack:
```rust
error: Failed to solve program: 'Failed to solve brillig function'
   ┌─ /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:27:12
   │
27 │     assert(x);
   │            -
   │
   = Call stack:
     1. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:7:17
     2. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:12:5
     3. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:18:9
     4. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:23:5
     5. /mnt/user-data/maxim/noir/test_programs/execution_failure/fold_nested_brillig_assert_fail/src/main.nr:27:12
```
