[WPE] Switch to use always complex text code path
https://bugs.webkit.org/show_bug.cgi?id=251579

Reviewed by Carlos Garcia Campos.

It's been a default on GTK since `https://commits.webkit.org/200076@main`.
It fixes a lot of WPE tests and lets us reuse already existing baselines
for passing GTK tests.

What are the changes outside of the LayoutTests directory? The interface doesn't load beyond 3000 files, and the changelog doesn't list them (while it's fine to avoid listing the changed baselines).

The only change in the source code is removing #if PLATFORM(GTK) in WebProcessPoolGLib.cpp:

WebKit/Source/WebKit/UIProcess/glib/WebProcessPoolGLib.cpp

Line 63 in dc9dac6

#if PLATFORM(GTK)

I think we don't need the environment variable or the platform-specific implementation code anymore.

[carlosgcampos]

The env var is still useful for debugging.
