Jonathan Wakely bd81327b03 libstdc++: Fix feature test macros in <version> for freestanding 
Some C++17 and C++20 feature test macros are only defined in <version>
for hosted builds, even though the features are supported for
freestanding.

All C++23 feature test macros are defined in <version> for freestanding,
but most of the features are only supported for hosted.

	(__cpp_lib_hardware_interference_size): Define for freestanding.
	(__cpp_lib_bit_cast): Likewise.
