[lldb][test] Remove duplicate testcase names in API test-suite (#97043)

In one of my recent PRs I mistakenly had two test-cases with the same
name, preventing one of them to run. Since it's an easy mistake to make
(e.g., copy pasting existing test-cases), I ran following sanity-check
script over `lldb/test/API`, which found couple of tests which were
losing coverage because of this (or in some cases simply had duplicate
tests):
```
import ast
import sys

filename = sys.argv[1]
print(f'Checking {filename}...')
tree = ast.parse(open(filename, 'r').read())

for node in ast.walk(tree):
    if not isinstance(node, ast.ClassDef):
        continue

    func_names = []
    for child in ast.iter_child_nodes(node):
        if isinstance(child, ast.FunctionDef):
            func_names.append(child.name)

    seen_func_names = set()
    duplicate_func_names = []
    for name in func_names:
        if name in seen_func_names:
            duplicate_func_names.append(name)
        else:
            seen_func_names.add(name)

    if len(duplicate_func_names) != 0:
        print(f'Multiple func names found:\n\t{duplicate_func_names}\n\tclass {node.name}\n\tfile: {filename}')
```

This patch fixes these cases.
