builtin: speed up string concatenation and repeat() method with vmemcpy instead of for loop for copying data (#18206) 
These changes almost do not speed up the program with the `-prod` flag,
since modern С compilers can do such optimization on their own, but in
normal mode, the performance gain is from 1.6 (concatenation) to 1.8 (repeat) times.

Concatenation:
Old (`for` loop):
Time (mean):          3.699 s +- 0.071 s  [User: 3.629 s, System: 0.069 s]
Range (min ... max):  3.548 s ... 3.741 s  10 runs

New (vmemcpy):
Time (mean):          2.305 s +- 0.065 s  [User: 2.263 s, System: 0.041 s]
Range (min ... max):  2.172 s ... 2.355 s  10 runs

`vmemcpy version` ran 1.60 +- 0.05 times faster than 'for loop version'

vlib Documentation

vlib is the term for all modules included by default with V and maintained as part of the V source code repository.

Some included modules depend on third party libraries, and these are kept separate in the thirdparty directory at the root level of the source repository.
