tst_QOpenGL: don't leak 1399341 byte(s) [...] in 1439 allocation(s)

Browse Source 
That's what asan reported for a run of this test executable.

Create `ctx` on the stack instead of the heap to fix the leaks.
For `fbo`, use a std::optional.

After these fixes, the test still leaks 64 bytes in 2
allocations. These seem to be QOpenGLSharedResourceGuards in a
QOpenGLFramebufferObject. Created QTBUG-134557 to track the issue.

- 68974d8e647febb80a47d9cf6ce9452f3ce4fa21 (fboHandleNulledAfterContextDestroyed())
- bb760d9514ed617ee8e7344152b3fa697b2c4171 (bufferMapRange()/bufferCreate())
- 0541516907da117c391b6c8d9820209673fcd9cd (vaoCreate())
