No checks for overflow's

Hi Team,

`https://github.com/Microsoft/ChakraCore/blob/master/pal/inc/pal.h#L4821`

Does not check for buffer overflows when copying to destination [MS-banned] (CWE-120).
Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy easily misused).

Request team to please have a look.

Cheers!

Start at pal/inc/pal.h around line 4821 and inspect the copy operation, its destination size, and the callers that provide the buffer. Confirm the overflow risk, choose a bounds-safe approach compatible with the project, and verify that the affected PAL behavior remains correct without permitting writes past the destination.
