all: transfer reflect.{SliceHeader, StringHeader} to unsafeheader.{Slice, String}
After we deprecated reflect.{SliceHeader, StringHeader}, it is recommended
to use unsafe.{Slice, String} to replace its work. However, the compiler
and linker cannot be migrated for the time being.
As a temporary strategy, using the "internal/unsafeheader" package like
other code is the most suitable choice at present.
For #53003.
