feat(true/false): add benchmarks for startup performance

[naoNao89]

Add benchmarks for true/false commands to measure startup performance. Includes both function call and process spawn benchmarks.

Closes #10837

I think --help/--version in not needed since they are not frequently used.

[oech3]

while someone might use true any strings via dummy symlinks.

oke

We want to sacrifice performance for cold uu_app() calls for hot pathes. So we don't want to bench them.
(In other words, bench for hot pathes are used to block accidentaly re-adding uu_app to hot pass by refactoring by someone)

oke, my changes satisfy that requirement
