InheritedFlags exceeds 8 bytes on Windows after ENABLE_TEXT_AUTOSIZING removal

Unreviewed build fix.
Removing ENABLE(TEXT_AUTOSIZING) unconditionally added the `autosizeStatus`
bitfield to InheritedFlags. Declared `unsigned` (4-byte) while its neighbours
are `unsigned char`, it opened a new storage unit under the Microsoft ABI
(clang-cl), growing InheritedFlags 8->12 and ComputedStyle 64->72 and tripping
their size static_asserts. Clang's Itanium ABI packs mixed-type bitfields, so
this was Windows-only. Declare it `unsigned char` to match; the value is a
uint8_t-backed OptionSet using only 5 bits, so range is unchanged.
