EGL: Add better errors for client API mismatch

Browse Source 
Because EGL ties client API support to configs, attempts to create
a context with an unavailable client API will fail with the unhelpful
"failed to find suitable config" error description.

This attempts to detect cases where there are usable configs for the
other client API and emit a hopefully more helpful error.

Related to #2173
