Enable Dynamic shape support via tensor virtual and physical resizing (#2340)

Summary:
X-link: https://github.com/pytorch/pytorch/pull/121598

Pull Request resolved: https://github.com/pytorch/executorch/pull/2340

## Context

This changeset lays the foundations for supporting dynamic shapes in the ExecuTorch Vulkan delegate via allowing Tensors to be resized in one of two ways:

1. Discarding underlying `vkImage` or `vkBuffer` and reallocating a new `vkImage` or `vkBuffer` with updated sizes. This method is intended to be used when the current `vkImage` or `vkBuffer` is not large enough to contain the new sizes.
2. Update the tensor's size metadata without reallocating any new resources. This allows shaders to interpret the underlying `vkImage` or `vkBuffer` as if it were smaller than it actually is, and allows command buffers to be preserved when sizes are changed.
