Core: fixed memory leak on configuration reload with PCRE2. In ngx_regex_cleanup() allocator wasn't configured when calling pcre2_compile_context_free() and pcre2_match_data_free(), resulting in no ngx_free() call and leaked memory. Fix is ensure that allocator is configured for global allocations, so that ngx_free() is actually called to free memory. Additionally, ngx_regex_compile_context was cleared in ngx_regex_module_init(). It should be either not cleared, so it will be freed by ngx_regex_cleanup(), or properly freed. Fix is to not clear it, so ngx_regex_cleanup() will be able to free it. Reported by ZhenZhong Wu, https://mailman.nginx.org/pipermail/nginx-devel/2023-September/3Z5FIKUDRN2WBSL3JWTZJ7SXDA6YIWPB.html
