build: delete checks for C89 standard headers

Browse source 
Delete checks and guards for standard C89 headers and assume these are
available: `stdio.h`, `string.h`, `time.h`, `setjmp.h`, `stdlib.h`,
`stddef.h`, `signal.h`.

Some of these we already used unconditionally, some others we only used
for feature checks.

Follow-up to 9c7165e96a #11918 (for `stdio.h` in CMake)

Closes #11940
