Use memmove() unconditionally in the code (#13647)

The memmove() function is C99 standard function [1] and check was left for
the PCRE2 bundled library. It can be simplified by passing the compile
option instead of checking always available function on current systems.
External PCRE2 library on the system doesn't need this.

Fix #79884: PHP_CONFIG_FILE_PATH is meaningless

It does not make sense to make assumptions about `PHP_CONFIG_FILE_PATH`
during build time, since that value is never used during run time on
Windows. Since there is no `--with-config-file-path` on Windows
either, we define `PHP_CONFIG_FILE_PATH` as `""`.

Fix #79532: sizeof off_t can be wrong

We have to actually determine the proper `SIZEOF_OFF_T`.
Interestingly, it is `4` on Windows x64.

We also have to prevent the redefinition in pg_config.h. The clean
solution would likely be to not include pg_config.h at all, but that's
out of scope for BC reasons for now.
