parted module not idempotent for esp flag and name (#40547)

* parted module not idempotent for esp flag and name

Fixes #40452

Currently the parted module doesn't take into account names with
spaces in them which leads to non-idempotent transactions on the
state of the system because the name comparison will never succeed.

Also, when the esp flag is set, parted infers the boot flag and the
parted module did not previously account for this. This lead to
non-idempotent transactions as well.
