Use numpy C-API for C implementations of Sort/Argsort

[ricardoV94]

Description

These are available (for argsort maybe for a single axis) in the numpy public C-API:

https://numpy.org/devdocs/reference/c-api/array.html#c.PyArray_Sort

https://numpy.org/devdocs/reference/c-api/array.html#c.PyArray_ArgSort

Using it for our own ops should be simpler than the already simple SearchSorted implementation:

pytensor/pytensor/tensor/signal/conv.py

Lines 68 to 71 in afb7695

	if self.mode == "full":
	valid_conv = type(self)(mode="valid")
	in1_bar = valid_conv(grad, in2[::-1])
	in2_bar = valid_conv(grad, in1[::-1])

Sort may act inplace, so we can add an inplace version of the Sort op as well (and be sure to copy when not enabled)
