Update forced_align method to only support batch Tensors

[nateanl]

Summary: Current design of forced_align accepts 2D Tensor for log_probs and 1D Tensor for targets. To make the API simple, the PR make changes to only support batch Tensors (3D Tensor for log_probs and 2D Tensor for targets).

Hey @None.
You merged this PR, but labels were not properly added. Please add a primary and secondary label (See https://github.com/pytorch/audio/blob/main/.github/process_commit.py).

---

Some guidance:

Use 'module: ops' for operations under 'torchaudio/{transforms, functional}', and ML-related components under 'torchaudio/csrc' (e.g. RNN-T loss).

Things in "examples" directory:

• 'recipe' is applicable to training recipes under the 'examples' folder,
• 'tutorial' is applicable to tutorials under the “examples/tutorials” folder
• 'example' is applicable to everything else (e.g. C++ examples)
• 'module: docs' is applicable to code documentations (not to tutorials).
  Regarding examples in code documentations, please also use 'module: docs'.

Please use 'other' tag only when you’re sure the changes are not much relevant to users, or when all other tags are not applicable. Try not to use it often, in order to minimize efforts required when we prepare release notes.

---

When preparing release notes, please make sure 'documentation' and 'tutorials' occur as the last sub-categories under each primary category like 'new feature', 'improvements' or 'prototype'.

Things related to build are by default excluded from the release note, except when it impacts users. For example:
* Drop support of Python 3.7.
* Add support of Python 3.X.
* Change the way a third party library is bound (so that user needs to install it separately).
