fix: crash when process name filter longer than 7

[happyharryh]

There are two issues in the codes related to the process name filter that result in a crash when the provided process name exceeds 7 characters in length:

1. The use of sizeof(Token) does not return the length of the string but instead gives the size of a pointer to TCHAR, which is always 8 bytes on the amd64 platform.

2. The strcpy_s function crashes when the length of the src (the third argument) exceeds the destsz (the second argument), as observed in my tests.

This PR resolves the crash by replacing strcpy_s with _tcsncpy_s.
