8c122e5d - [lldb][test] Make Linux cpuinfo check more robust (#160675)

[lldb][test] Make Linux cpuinfo check more robust (#160675) We were looking for any mention of the feature name in cpuinfo, which could have hit anything including features with common prefixes like sme, sme2, smefa64. Luckily this was not a problem but I'm changing this to find the features line and split the features into a list. Then we are only looking for exact matches. Here's the information for one core as an example: ``` processor : 7 BogoMIPS : 200.00 Features : fp asimd evtstrm crc32 atomics fphp asimdhp cpuid <...> CPU implementer : 0x41 CPU architecture: 8 CPU variant : 0x0 CPU part : 0xd0f CPU revision : 0 ``` (and to avoid any doubt, this is from a CPU simulated in Arm's FVP, it's not real) Note that the layout of the label, colon, values is sometimes aligned but not always. So I trim whitespace a few times to normalise that. This repeats once for each core so we only need to find one features line.
