Subject: [PATCH] docs: clarify evonode CPU requirements (x86-64-v3)

Update the evonode hardware requirements note to explicitly reference the
x86-64-v3 microarchitecture level instead of the vague 'Haswell or newer'
language. Notes that some older Haswell-era processors (e.g. Xeon E5 v3
with TSX disabled) may not be compatible, and that ARM64 is supported.

Closes dashpay/platform#2442
