perf python: Add __str__ and __repr__ functions to evsel
This allows evsel to be shown in the REPL like:
Python 3.11.9 (main, Jun 19 2024, 00:38:48) [GCC 13.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path.insert(0, '/tmp/perf/python')
>>> import perf
>>> x=perf.parse_events('cycles,data_read')
>>> print(x)
evlist([cycles,uncore_imc_free_running_0/data_read/,uncore_imc_free_running_1/data_read/])
>>> x[0]
evsel(cycles)
>>> x[1]
evsel(uncore_imc_free_running_0/data_read/)
>>> x[2]
evsel(uncore_imc_free_running_1/data_read/)
