rG4100bd6caa66: usr.bin: Remove intrinsic utilities

Summary

These utilities can only function correctly if implemented as shell
builtins and exist only because POSIX previously required them. As of
POSIX 2024, they have all been reclassified as intrinsic utilities and
are no longer required to exist in PATH. We can therefore retire them.
Cf. XBD 1.7, XRAT C.1.8, Austin Group bug 854.

Note that kill(1) is also considered an intrinsic utility (because
only the shell can interpret job IDs correctly), but we have a working
standalone implementation, which we will keep.

In builtin.1 we also have a chart where builtin utilities with standalone versions have asterisks, the asterisks for these utilities should also be removed in this commit I think

update builtins(1)

share/man/man1/builtin.1
166 ↗	(On Diff #168156)	Unrelated This is because this page is also called keybinds. Keyboard bindings is rendered on the next line. This was written so "Find in Page" for all possible vernacular would lead you to the top of this subsection. Therefore, please do not change it.

share/man/man1/builtin.1
166 ↗	(On Diff #168156)	Unimportant. Manual pages are supposed to be written in English, and this page isn't remotely long or complex enough for searchability to be an issue.
