Remove switches re-introduced to options.h by MR !792

The MR !792 (merged) has by accident re-introduced a number of switches to options.h only, which were already cleared out before. These switches are:

#define FIX_578_PARAMMC_ILD_BS                          /* FhG: Issue 578: transmitt also center ILD in band 0 when LFE is active in 3TC ParamMC */
#define FIX_UNCLR_ISSUE                                 /* VoiceAge: issue 574: Fix UNCLR mis-classifications in noisy speech stereo */
#define FIX_TCX_LOWRATE_LIMITATION                      /* VA: issue 577: TCX bitrate limitation only when DEBUGGING is active */
#define FIX_575_LOW_OVERLAP_PLC_RECOVERY                /* FhG: Issue 575 fix for PLC and transistion to TCX5*/
#define FIX_550_FIRST_FRAME_ACCESS                      /* Eri: Issue 550: TD Object renderer: first frame accesses wrong transport channel offsets */
#define FIX_550_FIRST_FRAME_ACCESS_ALT                  /* Eri: Issue 550: Should be merged with FIX_550_FIRST_FRAME_ACCESS above, or accepted at the same time */
#define FIX_569_TD_FILTER_LENGTH                        /* Eri: Issue 569: If an HRTF binary file exceeds the SFX_SPAT_BIN_MAX_FILTER_LENGTH the decoder crashes. This truncates the filter when generated from the model.  */
#define ISM_FB_16k4                                     /* VA: Issue: 579: change BW from SWB to FB in NxISM conditions to match the EVS codec */
#define FIX_580_PARAMMC_ENER_BURSTS                     /* FhG: issue 580: energy bursts due to ILD holding when energy relations change too much */
