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.
