Propertize the search region before anchoring call sites
flamegraph--collect-nested-call-sites uses `\_<...\_>' searches that
depend on syntax-table text properties (e.g. rbspy's `gsub!'/`any?'
need ruby-mode to mark `!'/`?' as symbol constituents). Apply them
explicitly: only Emacs 31's regexp engine triggers syntax-propertize
on demand during a match; on Emacs 30 the searches silently miss.
Emacs commit 6942d508f0c (bug#80600) made it optional there: by
deferring RE_SETUP_SYNTAX_TABLE_FOR_OBJECT's initialization, a regexp
match now propertizes its region on first syntax access, like the
sexp scanners already did.
