fix(Vehicle): remove initial connect outer timeouts causing slow-link failures (Stable_V5.1)

[DonLakeFlyer]

Stable backport of #15020.

Cherry-pick of 85a1c6b. Only conflict was test/Vehicle/CMakeLists.txt: dropped the TrajectoryPointsTest entries (master-only, not part of this fix) and kept the new StandardModesTest entries.
