Fix infinite recursion in expand_path when resolving paths with glob magic characters (#2036)

[Mahalaxmibejugam]

When calling expand_path(or the async _expand_path) with recursive=True on paths that resolve to filenames containing glob magic characters (such as [ or ?), the method would incorrectly treat these resolved paths as new glob patterns in the next recursive step. This led to either infinite recursion or unexpected FileNotFoundError when the characters were interpreted as character classes (e.g., file[1].txt searching for file1.txt).

To prevent this, assume_literal parameter is introduced to both expand_path and _expand_path:

• By default, it is False.
• When the method calls itself recursively on resolved paths (which we know are literals because they came from glob or find), it passes assume_literal=True.
• This bypasses the has_magic check and ensures the paths are treated as literals, stopping the infinite recursion and preventing false glob interpretations.

Fixes #2036
