perf parse-events: Tidy name token matching



Prior to commit 70c90e4a ("perf parse-events: Avoid scanning PMUs
before parsing") names (generally event names) excluded hyphen (minus)
symbols as the formation of legacy names with hyphens was handled in
the yacc code. That commit allowed hyphens supposedly making
name_minus unnecessary. However, changing name_minus to name has
issues in the term config tokens as then name ends up having priority
over numbers and name allows matching numbers since commit
5ceb5799 ("perf parse: Allow tracepoint names to start with digits
"). It is also permissable for a name to match with a colon (':') in
it when its in a config term list. To address this rename name_minus
to term_name, make the pattern match name's except for the colon, add
number matching into the config term region with a higher priority
than name matching. This addresses an inconsistency and allows greater
matching for names inside of term lists, for example, they may start
with a number.

Rename name_tag to quoted_name and update comments and helper
functions to avoid str detecting quoted strings which was already done
by the lexer.
