perf disasm: Refactor arch__find and initialization of arch structs

Switch arch__find to using an ELF machine number rather than a
string.

Rather than an array of fixed size arch structs turn the init functions
into new functions indexed by the ELF machine they correspond to.

This allows data to be stored with a struct arch with the container_of
trick, so the priv variable can be removed.

Switch to using the thread to find the arch rather than the evsel as the
evsel only has limited notions of the running thread upon which
disassembly is performed.

Factor out the e_machine and e_flags into their own struct to make them
easier to pass around.
