Added notes on DirAccess

Some notes are ported from FileAccess (for example file_exist)
Other notes were added when needed (for example when included on the non static version but not on the static version)
Other entirely new notes were added as well when required for example when getting a list of directories or if a directory exist or not

Clarified note at the top and made it more in line with the one found in file access

Because of this, to access resources in an exported project, it is recommended to use [ResourceLoader] instead of [FileAccess].

In practice, this means that since imported resources are stored in a top-level [code].godot/[/code] folder, only paths to [code].gd[/code] and [code].import[/code] files are returned (plus a few other files, such as [code]project.godot[/code] or [code]project.binary[/code] and the project icon). In an exported project, the list of returned files will also vary depending on [member ProjectSettings.editor/export/convert_text_resources_to_binary].
