[snpe] Add performance profile configuration support

usage:`... custom=Runtime:DSP,...,PerfProfile:"burst" ...`"
- Add support for configuring SNPE performance profiles through custom properties.
- The default performance profile is set to 'BALANCED'
REF:
```
typedef enum
{
  SNPE_PERFORMANCE_PROFILE_DEFAULT = 0,
  SNPE_PERFORMANCE_PROFILE_BALANCED = 0,
  SNPE_PERFORMANCE_PROFILE_HIGH_PERFORMANCE = 1,
  SNPE_PERFORMANCE_PROFILE_POWER_SAVER = 2,
  SNPE_PERFORMANCE_PROFILE_SYSTEM_SETTINGS = 3,
  SNPE_PERFORMANCE_PROFILE_SUSTAINED_HIGH_PERFORMANCE = 4,
  SNPE_PERFORMANCE_PROFILE_BURST = 5,
  SNPE_PERFORMANCE_PROFILE_LOW_POWER_SAVER = 6,
  SNPE_PERFORMANCE_PROFILE_HIGH_POWER_SAVER = 7,
  SNPE_PERFORMANCE_PROFILE_LOW_BALANCED = 8,
  SNPE_PERFORMANCE_PROFILE_EXTREME_POWER_SAVER = 9,
} Snpe_PerformanceProfile_t;
