Bug 286061 – [GLib] Remove all GLIB_CHECK_VERSION conditionals

• Status: RESOLVED
• Resolution: FIXED
• Component: Platform

[Adrian Perez]

The oldest Linux distribution we need to support in 2025 is Ubuntu 22.04,
which ships GLib 2.72.x - and all the GLIB_CHECK_VERSION condiotionals are
for previos versions:


  % rg -tcpp -F '#if GLIB_CHECK_VERSION(' --no-filename Source/{WTF,JavaScriptCore/,Web{Core,Kit}} | sort -u
  #if GLIB_CHECK_VERSION(2, 59, 0)
  #if GLIB_CHECK_VERSION(2, 60, 0)
  #if GLIB_CHECK_VERSION(2, 69, 0)
  #if GLIB_CHECK_VERSION(2, 69, 1)
  % rg -tcpp -F '#if GLIB_CHECK_VERSION(' Source/{WTF,JavaScriptCore/,Web{Core,Kit}} | wl -l
  24
  %

This means that we could change Source/cmake/Options{GTK,WPE}.cmake to check
for GLib 2.69.1+, and drop all the GLib-version conditional blocks.
