Improve behavioural consistency of unallocated (zero length) `IO::Buffer`. ( #9532 )
...
This makes the behaviour of IO::Buffer.new(0) and IO::Buffer.new.slice(0, 0) consistent.
Fixes https://bugs.ruby-lang.org/issues/19542 and https://bugs.ruby-lang.org/issues/18805 .

Use xfree for IO::Buffer
...
Since IO::Buffer is allocated using TypedData_Make_Struct, it must use
xfree to free the buffer otherwise it will cause more major GC to run.
Example:
```
10.times do
1_000_000.times { IO::Buffer.new(0) }
puts "oldmalloc_increase_bytes: #{GC.stat(:oldmalloc_increase_bytes)}, major_gc_count: #{GC.stat(:major_gc_count)}"
end
```
Before:
```
oldmalloc_increase_bytes: 14904176, major_gc_count: 3
oldmalloc_increase_bytes: 2399424, major_gc_count: 5
oldmalloc_increase_bytes: 5204640, major_gc_count: 6
oldmalloc_increase_bytes: 2199936, major_gc_count: 7

IO::Buffer#resize: Free internal buffer if new size is zero ( #7569 )
...
`#resize(0)` on an IO::Buffer with internal buffer allocated will
result in calling `realloc(data->base, 0)`. The behavior of `realloc`
with size = 0 is implementation-defined (glibc frees the object
and returns NULL, while BSDs return an inaccessible object). And
thus such usage is deprecated in standard C (upcoming C23 will make it
UB).
To avoid this problem, just `free`s the memory when the new size is zero.
