Old: `/usr/local/var/log/php-fpm.log`
New: `~/.config/valet/Log/php-fpm.log`
(We already put `~/.config/valet/Log/nginx-error.log` there)
This avoids ARM Mac differences in directory paths.
PHP's default is 128M, but it's becoming common practice to set the value to 512M in dev and production
Plus, currently homestead sets it to 512M as well.
PHP configs no longer support `#` for comments. Must use semicolons `;`.
Otherwise PHP may not start, and may show a confusing error in logs: `value is NULL for a ZEND_INI_PARSER_ENTRY`
This allows the valet configuration to stand separately from the default PHP config.
This benefits troubleshooting, makes customization of FPM workers and other settings easer
and allows for easier uninstallation.
Also renames any previously-existing `www.conf` pool config so it doesn't conflict with Valet nor run unnecessary additional processes.
