refs #6978, refs #6752, refs #21613, refs #24234 The `jsNoInt64`, `whenHasBigInt64`, `whenJsNoBigInt64` templates are replaced with bool constants to use with `when`. Weird that I didn't do this in the first place. The `whenJsNoBigInt64` template was also slightly misleading. The first branch was compiled for both no bigint64 on JS as well as on C/C++. It seems only `trandom` depended on this by mistake. The workaround for #6752 added in #6978 to `times` is also removed with `--jsbigint64:on`, but #24233 was also encountered with this, so this PR depends on #24234.
