remove find_package(Python) in libcudf build

[jameslamb]

Description

Nothing in libcudf's CMake should need a Python interpreter or linking to Python components. This proposes removing the find(Python) there, to simplify that build:

cudf/python/libcudf/CMakeLists.txt

Lines 37 to 38 in 955b1f4

	# Find Python early so that later commands can use it
	find_package(Python 3.10 REQUIRED COMPONENTS Interpreter)

/ok to test

I wonder if we need to change our CMake codeowners. This didn't trigger for CMake code ownership, but probably should.

cudf/.github/CODEOWNERS

Line 11 in 955b1f4

cpp/CMakeLists.txt @rapidsai/cudf-cmake-codeowners

should probably be just CMakeLists.txt rather than cpp/CMakeLists.txt.

If you agree, we can combine it into this PR or I can make a new one.

Yep I agree!
