Drop XP <= 9 compatibility

[thekid]

Scope of Change

This RFC suggests dropping compatibility for XP 9 (and lower).

Rationale

XP 9.0.0 was released 2017-09-24, more than 4 years ago and has no support for PHP 8, released roughly a year ago at the time of writing.

Functionality

Libraries will drop support for XP 9 and lower with their next major release.

The typical diff will look something like this:

-"xp-framework/core": "^10.0 | ^9.0 | ^8.0 | ^7.0"
+"xp-framework/core": "^10.0"

We can also bump minimum library requirements by looking when they started supporting XP 10 when doing so, e.g.:

-    "xp-framework/http": "^10.0 | ^9.0 | ^8.0 | ^7.0",
-    "xp-framework/zip": "^9.0 | ^8.0 | ^7.0",
+    "xp-framework/http": "^10.0 | ^9.0",
+    "xp-framework/zip": "^9.0 | ^8.0",

This means libraries can use MemoryOutputStream::bytes() instead of getBytes(). The former was added in XP 9.8.0, see https://github.com/xp-framework/core/releases/tag/v9.8.0
