[dataset] simplify IsSubsetOf() (#10292)

Browse Source 
This commit adds a method `Dataset::IsSubsetOf()` to check whether one
dataset is a subset of another. A dataset is considered a subset if
all its TLVs, excluding Active/Pending Timestamp and Delay Timer
TLVs, are present in the other dataset with exactly matching values.

This new method simplifies `Dataset::Info::IsSubsetOf()`. The unit
test `test_dataset` is updated to validate the `IsSubsetOf()()`
method.
