[fpc-pascal] TProcessUTF8 doc - 2

[Alexey Tor.]

a)

https://lazarus-ccr.sourceforge.io/docs/lazutils/utf8process/tprocessutf8.html

here we have 2-3 items depre - ApplicationName, CommandLine. but list 
shows no special mark. confusing. it shows [rw] marks, pls add near the 
[deprecated] marks.

b)

https://lazarus-ccr.sourceforge.io/docs/fcl/process/tprocess.environment.html

 >If it is empty, the environment of the current process is passed on to 
the new process.

need more info-- what happens if  I set one line there- process inherits 
old env, and my one line is added? how to ADD one line to old env?

--> write info to the docs.
