AGESA f15tn: Drop `IDSOPT_ASSERT_ENABLED`

The `ASSERT` macro is already defined in `src/include/assert.h`, and
AGESA's definition is never used. On Asus A88XM-E, toggling the value of
the `IDSOPT_ASSERT_ENABLED` macro does not change the resulting binary
when using reproducible builds. Attempting to use AGESA's definition of
the `ASSERT` macro results in build errors:

 In file included from src/vendorcode/amd/agesa/f15tn/Proc/CPU/Feature/cpuDmi.c:56:
 src/vendorcode/amd/agesa/f15tn/Proc/CPU/Feature/cpuDmi.c: In function 'GetType4Type7Info':
 src/vendorcode/amd/agesa/f15tn/Include/Ids.h:371:33: error: statement with no effect [-Werror=unused-value]
      #define ASSERT(conditional) ((conditional) ? 0 : IdsAssert (STOP_CODE));

Given that coreboot's definition of `ASSERT` is more useful, drop
AGESA's broken definition and the useless `IDSOPT_ASSERT_ENABLED` macro.
Also remove the `IdsAssert` function, as it is no longer used anywhere.

Tested with BUILD_TIMELESS=1, Asus A88XM-E remains identical.

- * @def ASSERT
- *  Test an assertion that the given statement is True.

- *  is generated to halt the program. Used for testing for fatal errors that
