ofAppEGLWindow.cpp no longer compiles, which breaks a native build on 32-bit ARM Linux (armv6l/armv7l), where the makefile builds the EGL/GLES window. On x86_64 and aarch64 the GLFW window is used and this file is skipped, so it went unnoticed.

Errors from a native armv7l build (Debian bookworm armhf):

ofAppEGLWindow.cpp:149:31: error: 'str' was not declared in this scope
ofAppEGLWindow.cpp:444:37: error: 'struct ofAppEGLWindowSettings' has no member named 'glesVersionMajor'
ofAppEGLWindow.cpp:445:53: error: expression cannot be used as a function
ofAppEGLWindow.cpp:170:1: error: control reaches end of non-void function [-Werror=return-type]

Changes:

• CASE_STR now does case x: return y instead of assigning to an undeclared str. This also fixes the missing return.
• settings.glesVersionMajor() / glesVersionMinor() become getGLESVersionMajor() / getGLESVersionMinor(). ofGLESWindowSettings exposes plain members plus those getters, not methods with the old names.

Testing: not yet compiled on a Pi-class target locally. It is being checked by a native armv7l build in https://github.com/danoli3/ofLinuxTestScripts, and I'll update this PR with the result.

Verified on a native armv7l build (Debian bookworm armhf userland, GCC 12) in https://github.com/danoli3/ofLinuxTestScripts, using this change on top of current master: ofAppEGLWindow.cpp now compiles and the core builds, and the unit tests run. The four errors in the description are gone.

Unrelated to this change: that run still ends with one unit test failure (ofRectangleTests crashes in ofBaseApp setup under QEMU), which I'm looking at separately.
