[ET-VK] Enable Dynamic shape support via tensor virtual and physical resizing (#121598)
Summary:
## 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.
Test Plan: Check CI. Tests have also been added to `vulkan_compute_api_test` that test the two methods of tensor resizing.
