Improve 'trusted-set-cookie-reload' — prevent infinite reload for constantly changing values

[jellizaveta]

Currently, if we pass in the date values for trusted-set-cookie-reload to the arguments, it causes an infinite reload because the value we are comparing inside the scriptlet function is constantly changing

Steps to reproduce:

1. Add to the user rules:
   example.org#%#//scriptlet('trusted-set-cookie-reload', 'example', '$currentISODate$')
2. Go to example.org

Same with uBlock Origin.

Perhaps such cases need to be rewritten into two scriptlets:

example.org#%#//scriptlet('set-cookie', 'example', '$currentISODate$')
example.org#%#//scriptlet('set-cookie-reload', 'dummy', '1')

The downside is that the site may detect the dummy cookie and it will be difficult to generate new names in MV3 (cookies valid longer than the open browser session - closed from time to time). Additionally, large sites may not like cookies with strange names or baking them too early.
