perf parse-events: Fix for term values that are raw events

Raw events can be strings like 'r0xead' but the 0x is optional so they
can also be 'read'. On IcelakeX uncore_imc_free_running has an event
called 'read' which may be programmed as:
```
$ perf stat -e 'uncore_imc_free_running/event=read/' -a sleep 1
```
However, the PE_RAW type isn't allowed on the right of a term, even
though in this case we just want to interpret it as a string. This
leads to the following error on IcelakeX:
```
$ perf stat -e 'uncore_imc_free_running/event=read/' -a sleep 1
event syntax error: '..nning/event=read/'
                                  \___ parser error
Run 'perf list' for a list of valid events

 Usage: perf stat [<options>] [<command>]

    -e, --event <event> event selector. use 'perf list' to list available events
```
Fix this by allowing raw types on the right of terms and treat them as
strings, just as is already done for PE_LEGACY_CACHE. Make this
consistent by just entirely removing name_or_legacy and always using
name_or_raw that covers all three cases.
