Update base for Update on "[ET-VK] Adding UniformData struct in vTensor class to store uniform data, which will be stored using shared ptr and can be shared with push constants."

This diff adds a new struct called `UniformData` in the `vTensor` class to store uniform data, which can be shared with push constants. The `UniformData` struct contains the sizes, strides, and logical limits of the tensor, as well as the number of elements in the tensor.

Diff adds `Attribute` enum to Tensor class to enumerate attributes supplied to dispatch and `UniformData` class to store tensor data supplied as uniforms to op shaders.

The diff also adds write_attribute function to UniformData class to write attribute data to a given memory.
