grep/pcre2: use pcre2_maketables_free() function
Make use of the pcre2_maketables_free() function to free the memory allocated by pcre2_maketables(). At first sight it's strange that 10da030ab75 (grep: avoid leak of chartables in PCRE2, 2019-10-16) which added the free() call here doesn't make use of the pcre2_free() the author introduced in the preceding commit in 513f2b0bbd4 (grep: make PCRE2 aware of custom allocator, 2019-10-16). The reason is that at the time the function didn't exist. It was first introduced in PCREv2 version 10.34, released on 2019-11-21. Let's make use of it behind a macro. I don't think this matters for anything to do with custom allocators, but it makes our use of PCREv2 more discoverable. At some distant point in the future we'll be able to drop the version guard, as nobody will be running a version older than 10.34.
