Do not use multiple processes

Brave uses over a dozen different processes. Right now, for example, it shows 17 processes on my System Monitor. Two of them using about 100MiB memory, one 88, one 79, etc. Right now they use little of CPU.

In this way, I have difficulty assessing the overall resource usage by Brave. Normally, if I suspect my system is low on memory, I sort processes by memory and see who are the greediest. With brave spreading its usage over multiple processes, it would not pop up even if it is the greediest.

Actually, I would like to switch from Firefox as my main browser, and Brave appears very attractive. However, this inability to assess its overall resource usage stops me.

Please consider merging all processes into one, different threads.
