[druntime] Replace old AliasDeclaration syntax for 2024 edition

[ntrel]

See #22244. Needed for #22275. @thewilsonator.

I used dfix master (recently updated dlang-community/dfix#63).

I did:

• revert a few unrelated diff hunks it produced (trailing struct semi-colons core/sys/linux/input.d)
• manually update an alias in a mixin: core/sys/linux/link.d
• put a stripped out comment back in core/sys/windows/basetyps.d: alias UUID = GUID, /*IID, CLSID, */FMTID = GUID, uuid_t = GUID;

There's at least 2 long aliases with multiple components that could be broken up:

• at the start of core/sys/windows/commdlg.d
• in core/sys/windows/wincrypt.d

E.g.:

-alias UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow
-    LPCCHOOKPROC, LPCFHOOKPROC, LPFRHOOKPROC, LPOFNHOOKPROC,
-    LPPAGEPAINTHOOK, LPPAGESETUPHOOK, LPSETUPHOOKPROC, LPPRINTHOOKPROC;
+alias LPCCHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow, LPCFHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow, LPFRHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow, LPOFNHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow, LPPAGEPAINTHOOK = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow, LPPAGESETUPHOOK = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow, LPSETUPHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow, LPPRINTHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow;

It might be better to put each ident = on a new line:

+alias LPCCHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow,
	LPCFHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow,
	LPFRHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow,
	LPOFNHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow,
	LPPAGEPAINTHOOK = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow,
	LPPAGESETUPHOOK = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow,
	LPSETUPHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow,
	LPPRINTHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow;

or reuse the first ident as the target of the other idents:

alias LPCCHOOKPROC = UINT_PTR function (HWND, UINT, WPARAM, LPARAM) nothrow, LPCFHOOKPROC = LPCCHOOKPROC, LPFRHOOKPROC = LPCCHOOKPROC, LPOFNHOOKPROC = LPCCHOOKPROC, LPPAGEPAINTHOOK = LPCCHOOKPROC, LPPAGESETUPHOOK = LPCCHOOKPROC, LPSETUPHOOKPROC = LPCCHOOKPROC, LPPRINTHOOKPROC = LPCCHOOKPROC;
