Refactor bundle derive (#19749)
# Objective

- Splitted off from  #19491
- Make adding generated code to the `Bundle` derive macro easier
- Fix a bug when multiple fields are `#[bundle(ignore)]`

## Solution

- Instead of accumulating the code for each method in a different `Vec`,
accumulate only the names of non-ignored fields and their types, then
use `quote` to generate the code for each of them in the method body.
- To fix the bug, change the code populating the `BundleFieldKind` to
push only one of them per-field (previously each `#[bundle(ignore)]`
resulted in pushing twice, once for the correct
`BundleFieldKind::Ignore` and then again unconditionally for
`BundleFieldKind::Component`)

## Testing

- Added a regression test for the bug that was fixed
