ad88816c - [quant][core][gpu][feature] Added support for float->quantized cuda tensor copying (#76177)

[quant][core][gpu][feature] Added support for float->quantized cuda tensor copying (#76177) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/76177 Previously, support for copying a fp tensor to a quantized tensor was limited to CPU tensors. This PR extends the support to GPU tensors. A corresponding test was added to test_qtensor_float_assignment for cuda tensors Test Plan: ``` python test/test_quantization.py -k test_qtensor_float_assignment ``` Imported from OSS Differential Revision: D35817832 D35817832 Reviewed By: jerryzh168 Pulled By: dzdang fbshipit-source-id: e5a4a0bb2d8a56f3f1a88806a534b5cb38275cf2 (cherry picked from commit 9173e07b51bb1b853244b205ddf3e36000f01b64)
