Create ready files of loader process

A new function is added to create a ready file of the loader.
The function creates the file that the path is
"/run/user/<uid>/.<loader_name>.ready".

Support Launch Mode

The platform developer can set the launch mode of the app execution about
the loader using the configuration file.
There are 4 modes as below:
 1. Mode=Previous_Operation:
  - This mode is the original behavior. If the loader is not preapred,
  the application will be executed using fork() & execv().
 2. Mode=Default_Operation:
  - This mode is the default behavior from Tizen 8.0.
  - If the loader is not prepared and the loader is running, the launchpad
  waits until the loader is prepared. And then, the launch request will
  be delivered to the loader process.
 3. Mode=Always_Loader:
  - This mode is that the application will be  always executed using
  the loader process.
  - Even if the loader process is not executed, the launch request will
  be delivered to the loader process.
  - If the loader process is not executed, the launchpad executes
  the loader process when getting the launch request.
  - After processing the launch request, the launchpad executes the loader
  process when the pending request exists.
 4. Mode=Always_Loader_Without_CPUChecker:
  - This mode is the modified version of the "Mode=Always_Loader".
  - The loader process will be executed after processing the launch request.

Remove blocking and unblocking all sub threads

If the launchpad library tries to block the sub thread, the main thread
can be blocked. Because, if the sub thread calls the dlsym(), the global
mutex is locked. In this case, the main thread can be blocked by the mutex.

process can be blocked when the child process tries to allocate the memory.

Modify CloseAllFds method

While searching the fd directory using std::filesystem::directory_iterator,
we can close the file descriptor of the directory_iterator. In this case,
the std::filesystem::filesystem_error exception will be thrown.
To avoid throwing the exception, the method uses std::vector to store
file descriptors. And then, the method closes all file descriptors using
the vector.
