Where is delay_ms function declared?

My guess...

If you mean where is it located, it's just another function that CCS supplies, so it's 'declared' within the compiler itself, same as printf(), getc(), rand(), etc.

It is _prototyped_ in the header file for the chip. This tells things like
debuggers it's 'nature', but the actual code as Temtronic says is 'built in' to the
compiler.
If you look at the prototypes in the chip's header, you will see these declared
as '_bif'. This is code for 'built in function'.
