Fixes a regression since 5.5, where `ScanDirectoryFilesRecursively` no
longer does the "recursively" part due to `path` being `static`.

The issue was once already fixed in
5530a3ceb8
but recently made it back it in.

Found some issues with output size when padding required, just re-implemented both functions from scratch.

Note that returned output size considers the NULL terminator as an additional byte.

- All `char *` refer to text strings
- All `unsigned char *` refer to generic byte arrays

InitWindow() prints CWD during initialization,
but ChangeDirectory() does not, which is quite confusing when you start
messing with CWD. Now said function should log similar message.

* [rcore] fix crash in InitWindow, due to unchecked result of InitPlatform

Check the result of InitPlatform(), if it isn't 0, report the Error
and return. This prevent crashes and allows for gracefully aborting
or recovering by checking IsWindowReady().

Partially-fixes: https://github.com/raysan5/raylib/issues/4801

* [rcore] style: store the result of InitPlatform() before checking it

Small style change that doesn't impact how the code behaves here.
Variable 'result' is not used anywhere else in this block,
it's just for compliance with Raylib's coding conventions.

* [rcore] use LOG_WARNING when InitPlatform() fails

...as this is preferred over LOG_ERROR.
