Subject: [PATCH 1/3] [lldb][test] Fix the test TestArrayFromStdModule.py

This patch fixes the error https://lab.llvm.org/staging/#/builders/195/builds/4464
```
File "llvm-project/lldb/test/API/commands/expression/import-std-module/array/TestArrayFromStdModule.py", line 55, in test
    self.expect_expr("a.at(0)", result_type=value_type, result_value="3")
Hint: The expression tried to call a function that is not present in the target, perhaps because it was optimized out by the compiler.
```
Note adding the usage of `a.at(0)` to main.cpp did not help.
It is the alternative to #98701.
