bpo-40334: Make the PyPegen* and PyParser* APIs more consistent (pythonGH-19839)
This commit makes both APIs more consistent by doing the following: - Remove the `PyPegen_CodeObjectFrom*` functions, which weren't used and will probably not be needed. Functions like `Py_CompileStringObject` can be used instead. - Include a `const char *filename` parameter in `PyPegen_ASTFromString`. - Rename `PyPegen_ASTFromFile` to `PyPegen_ASTFromFilename`, because its signature is not the same with `PyParser_ASTFromFile`.
