[clang-tidy]: readability-simplify-boolean-expr wants to use DeMorgan's theorem on macros despite IgnoreMacros

[nick-potenski]

clang-tidy produces a readability-simplify-boolean-expr warning to simplify expressions with macros using DeMorgan's theorem despite readability-simplify-boolean-expr.IgnoreMacros being set to true.

Simplified test case:

#define is_a_favorite_number(_i) (_i == 42 || _i == 3 || _i == 1000000)

bool UseNumber(int i) { return i >= 0 && !is_a_favorite_number(i); }

.clang-tidy config:

---
Checks:
    '-*,
    readability-simplify-boolean-expr
    '
CheckOptions:
    - key:      readability-simplify-boolean-expr.IgnoreMacros
      value:    true

Produces the following:

1 warning generated.
test_bool_simplification.cpp:4:42: error: boolean expression can be simplified by DeMorgan's theorem [readability-simplify-boolean-expr,-warnings-as-errors]
    4 | bool UseNumber(int i) { return i >= 0 && !is_a_favorite_number(i); }
      |                                          ^~~~~~~~~~~~~~~~~~~~~~~~
