hellofromTonya 8d04dc7e1c Upgrade/Install: Micro-optimizations for getting plugin_file in plugins loader loop.
RE: Plugins Dependencies.

The following micro-optimization improvements are included for finding each plugin's file relative to the plugins' directory within `wp-settings.php`:

* Move `trailingslashit()` before `foreach()`.

The path to the plugin directory is a constant. Invoking the `trailingslashit()` within the loop for each plugin is unnecessary and less performant.

This commit moves the plugin directory logic to before the loop. The result: the logic will now run 1x instead of Px where P represents the number of active and valid plugins to be loaded.

* Use `substr()` instead of `str_replace()` to extract the plugin's file relative to the plugins' directory.

`substr()` is more performant than `str_replace()`.

Why?

Per the PHP handbook:
>"This function returns a string or an array with all occurrences of search in subject replaced with the given replace value."

`str_replace()` searches the entire string to find and replace each substring occurrence.

whereas

>"Returns the portion of string specified by the offset and length parameters."

`substr()` starts at the given offset and stops at the given (or end of the) string length.

In other words, `substr()` iterates over less of and only a specific portion of the given input string, whereas `str_replace()` iterates through the entire string searching for matches (plural).
