Qt.preprocess source arguments deprecated

The qt.preprocess method currently has this signature: qt.preprocess(name: str | None, *srcs: str), this is not a nice signature because it's confusing, and there's a sources keyword argument as well. Both of these pass sources through unmodified, this is a bit of a historical accident, and not the way that any other module works. These have been deprecated, so instead of:

sources = qt.preprocess(
    name,
    list, of, sources,
    sources : [more, sources],
    ... # things to process,
)

executable(
    'foo',
    sources,
)

use

processed = qt.preprocess(
    name,
    ... # thins to process
)

executable(
    'foo',
    'list', 'of', 'sources', 'more', 'sources', processed,
)
