feat(indent): Always check for b:org_indent_mode if available

[kristijanhusak]

Always check for vim.b.org_indent_mode before applying indentation to the buffer. If it's true, treat all indentations in a buffer as if the configuration has org_startup_indented enabled.

@PriceHiller can you review and test this to see if it works ok?
