Godot core needs MD5/SHA256/AES/Base64 which used to be provided by
separate libraries.
Since we bundle mbedtls in most cases, and we can easily only include
the needed sources if we so desire, let's use it.

To simplify library changes in the future, and better isolate header
dependencies all functions have been wrapped around inside a class in
`core/math/crypto_base.h`.

If the mbedtls module is disabled, we only bundle the needed source
files independently of the `builtin_mbedtls` option.
If the module is enabled, the `builtin_mbedtls` option works as usual.

Also remove some unused headers from StreamPeerMbedTLS which were
causing build issues.

Export paths are now saved as relative paths

Auto-change file extension in EditorFileDialog when filter changes

HTTPRequest used to have its own `status` variable but it would never be
updated since the status of the client would be used instead.
This caused potential crashes in some edge cases.
The `status` variable is now removed, and the client status is used in
checks instead.

doc: Complete GlobalScope documentation

Add a configuration warning when using Ignore mouse filter with tooltip

Draw the script editor's line length guideline below characters

 Added example on how to use RandomNumberGenerator

If the target directory does not exist, it will be recursively created.

Export paths are now saved as a relative to the projects base directory

Renamed relative_to function to final_path_from_relative which takes a relative path and outputs the final path from a string that represents a directory.
Added relative_path_from_final which takes in a final path and outputs a relative path if possible. If not possible it outputs the relative path that represents the current directory.
If the target directory does not exist when exporting the project, then it is recursively created.

Removed final_path_from_relative function

Changed DirAccess into DirAccessRef for automatic object destruction

This closes #30144.
