Fix and add unit tests for Caps Word to work with Unicode Map, Auto Shift, Retro Shift. (#17284)

* Fix Caps Word and Unicode Map

* Tests for Caps Word + Auto Shift and Unicode Map.

* Fix formatting

* Add additional keyboard report expectation macros

This commit defines five test utilities, EXPECT_REPORT, EXPECT_UNICODE,
EXPECT_EMPTY_REPORT, EXPECT_ANY_REPORT and EXPECT_NO_REPORT for use with
TestDriver.

EXPECT_REPORT sets a gmock expectation that a given keyboard report will
be sent. For instance,

  EXPECT_REPORT(driver, (KC_LSFT, KC_A));

is shorthand for

  EXPECT_CALL(driver,
      send_keyboard_mock(KeyboardReport(KC_LSFT, KC_A)));

EXPECT_UNICODE sets a gmock expectation that a given Unicode code point
will be sent using UC_LNX input mode. For instance for U+2013,

  EXPECT_UNICODE(driver, 0x2013);

expects the sequence of keys:

  "Ctrl+Shift+U, 2, 0, 1, 3, space".

EXPECT_EMPTY_REPORT sets a gmock expectation that a given keyboard
report will be sent. For instance

  EXPECT_EMPTY_REPORT(driver);

expects a single report without keypresses or modifiers.

EXPECT_ANY_REPORT sets a gmock expectation that a arbitrary keyboard
report will be sent, without matching its contents. For instance

  EXPECT_ANY_REPORT(driver).Times(1);

expects a single arbitrary keyboard report will be sent.

EXPECT_NO_REPORT sets a gmock expectation that no keyboard report will
be sent at all.

* Add tap_key() and tap_keys() to TestFixture.

This commit adds a `tap_key(key)` method to TestFixture that taps a
given KeymapKey, optionally with a specified delay between press and
release.

Similarly, the method `tap_keys(key_a, key_b, key_c)` taps a sequence of
KeymapKeys.

* Use EXPECT_REPORT, tap_keys, etc. in most tests.

This commit uses EXPECT_REPORT, EXPECT_UNICODE, EXPECT_EMPTY_REPORT,
EXPECT_NO_REPORT, tap_key() and tap_keys() test utilities from the
previous two commits in most tests. Particularly the EXPECT_REPORT
macro is frequently useful and makes a nice reduction in boilerplate
needed to express many tests.
