Add Respfile support for soong_zip.

Sometime the size of our command line passed to soong_zip go program
exceeds the cmdline size limit. So add an RespFile support with "@" special
character prefix.

The args in the cmdline will be considered together with the
args in RespFile during soong_zip running.

Test: real tests in my local machine, and compare the
res/libphonenumber.jar before and after changes.

./cmd -o test.zip '""'-C -> [./cmd,-o,test.zip,""-C]
./cmd -o test.zip '-C -f -> [./cmd,-o,test.zip,-C -f]
./cmd -o test.zip '\"'-C -f -> [./cmd,-o,test.zip,\"-C -f]
./cmd -o test.zip '\\'-C -f -> [./cmd,-o,test.zip,\\-C -f]
./cmd -o test.zip '\a'-C -f -> [./cmd,-o,test.zip,\a-C -f]

./cmd -o test.zip \'-C -> [./cmd,-o,test.zip,'-C]
./cmd -o test.zip \\-C -> [./cmd,-o,test.zip,\-C]
./cmd -o test.zip \"-C -> [./cmd,-o,test.zip,"-C]

./cmd -o test.zip "'"-C -> [./cmd,-o,test.zip,'-C]
./cmd -o test.zip "\\"-C -f -> [./cmd,-o,test.zip,\a-C -f]
./cmd -o test.zip "\""-C -f -> [./cmd,-o,test.zip,"a-C -f]
