TBL UT failure when max table size is increased

[dmknutsen]

Describe the bug
TBL unit tests do not always initialize a memory pool large enough for table load buffers prior to unit test execution.

To Reproduce
Increase the size of the max allowable table sizes and run unit test.

Example:
#define CFE_PLATFORM_TBL_MAX_DBL_TABLE_SIZE 131072
#define CFE_PLATFORM_TBL_MAX_SNGL_TABLE_SIZE 131072
#define CFE_PLATFORM_TBL_BUF_MEMORY_BYTES (8388608*2)
#define CFE_PLATFORM_TBL_MAX_SIMULTANEOUS_LOADS 4
