  [OpenMP] Fix taskgraph dependency tracking, memory access, and initialization (#136837)

This commit resolves multiple issues in the OpenMP taskgraph implementation:
- Fix a potential use of uninitialized is_taskgraph and tdg fields when a task is created outside of a taskgraph construct.
- Fix use of task ID field when accessing the taskgraph’s record_map.
- Fix resizing and copying of the successors array when its capacity is exceeded.

Fixes memory management flaws, invalid memory accesses, and uninitialized data risks in taskgraph operations.
