Include EasyPrivacy by default

[bbondy]

@darkdh just updated the DEPS to point to the new adblock which has EasyPrivacy by default.

CC @kjozwiak @srirambv @LaurenWags

Testing notes:
This new version uses adblock v4 format. The new ad-block v4 lib is not compatible with the old v3 DAT file which gets downloaded to the profile directory for regional DAT files and the default ad-block file ABPFilterParserData.dat.

Please make sure that profiles which already have the old v3 .dat file gets overwritten for both ABPFilterParserData.dat and for regional list .DAT files (which have a UUID for the filename) get upgraded. If it tries to use the old DAT file with the new library, then it will crash so this needs explicit testing.

Verified with macOS (@kjozwiak and @LaurenWags) using

• 0.23.19 178c3fb
• Muon 7.1.3
• libchromiumcontent 67.0.3396.87

Went through the following test case when verifying the above:

* visited a few media websites where there's a lot of ads using `0.22.810` (also logged into a few websites)
* enabled a few regional blocklists via `about:adblock`
* Went into brave profile folder and noticed the following files:  `ABPFilterParserData.dat`, `1088D292-2369-4D40-9BDF-C7DC03C05966.dat`, `7DC2AC80-5BBC-49B8-B473-A31A1145CAC1.dat` & `6A0209AC-9869-4FD6-A9DF-039B4200D52C.dat`
* noted the size of each those files and made a copy to compare after updating

Updated to `0.23.19`and ensured that:

* files mentioned above look updated (size changed)
* loaded a bunch of websites and ensured that blocking as still working (English/Polish/Russian)
* relaunched the browser a few times to make sure there's no crashes
