[BUG] Runtime `default_ptx_arch` setting needs to consider NVRTC supported architectures

[shi-eric]

Bug Description

Currently, it is possible to ask NVRTC to compile code for an architecture it does not recognize, when it should really be falling back to the default minimum architecture value of 75.

This appears to be due to the following code that sets the runtime.default_ptx_arch to the lowest value of architectures on the system without checking that each architecture is supported by NVRTC.

warp/warp/context.py

Lines 4098 to 4100 in 3889aec

	eligible_archs = [d.arch for d in self.cuda_devices if d.arch >= self.default_ptx_arch]
	if eligible_archs:
	self.default_ptx_arch = min(eligible_archs)
