share: introduce config option to store requires in .hg/store

This introduces a config option which enabled stores the requirements on a
repository in store instead.

When enabled, `.hg/requires` will contain the `share-safe` requirement which
marks that the requirements are present in the store.
This is done so that repository requirements can be shared with shares made
using `hg share` command.

After this patch, `hg share` checks whether the source repository has
share-safe requirement, if yes, it does not copy the requirements.

Test for the new functionality is added and a test case in exitsing share tests
is also added.
