[Support][Chrono] Use explicit cast of text output of time values.
rL316419 exposed a platform specific issue where the type of the values
passed to llvm::format could be different to the format string.
Debian unstable for mips uses long long int for std::chrono:duration,
while x86_64 uses long int.
For mips, this resulted in the value being corrupted when rendered to a
string. Address this by explicitly casting the result of the duration_cast
to the type specified in the format string.
