BaseTools: Limit command line length.

Browse Source 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2528

Currently, CL command contains multiple C files will be compiled,
and that caused command line too long, which may trigger build error.

In order to solve this issue, the following rules is used in this scene:

If the number of C files is greater than one, a txt file will be used
to record these C files, and replaces the corresponding content in
command line with the file name.

Else (only one C file listed in the command line), the length of the
whole CL command line will determine whether use a file to record. If
the length exceeds the limited max length, use the recording file; else
C file name directly listed in the command line
