[Py3.10] Allow floats to be imported as Long (#81372)
Thus avoiding `TypeError: 'float' object cannot be interpreted as an integer` when trying to create integer tensor from floating point values
Use `c10::checked_convert` to detect overflows during tensor construction from scalars. Modify sparse_csr test that violated this rule
Fixes #69319
Tested in #81233
