ls/ls-url: do not show entry with size<=0 for a directory (#10687)

ls/ls-url: do not show size=0 when the entry is a directory

3.13 support for Windows (#10667)

python/cpython#113829 changed `os.path.isabs` on Windows to not consider a path starting a single backslash to be an absolute path.

We do a lot of naive `posixpath` to `ntpath` conversions, and it broke DVC in multiple places. DVC is likely broken in many other places, and these bugs are difficult to identify.

In this commit, I have tried to fix in the places where the tests failed. And mostly by trying to imitate pre-3.13 behaviour.
Some of the changes may not be correct but keeps the old behaviour in place.

Also re-enabled the CI for all Python versions supported for Windows.

Fix #10638 : makes remove return correct list when used with both `--…

…queue` and `-A` (#10641)

* fixed a bug where using both `--queue` and `-A` would yield a "removed" list without the queued experiments

* added a test to validate the fix

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* clearer name for test
