[Android] Implement pagination for publisher list

[kjozwiak]

Created duplicate of #9607 as this was placed in 1.9.x for desktop. If there's another HF for desktop, #9607 will be moved into that milestone. However, this will most likely go out first in the 1.18.x HF1 on Android that will include the CR bump.

Test plan

See brave/brave-core#5458

• Original PR --> Adds pagination to publisher list brave-core#5458
• Uplift into 1.9.x --> Adds pagination to publisher list (uplift to 1.9.x) brave-core#5471
• Uplift into 1.8.x --> Adds pagination to publisher list (uplift to 1.8.x) brave-core#5472
