Represents a single bit field in an integer, similar to BitField.
It can be used in most places that need a BitField, as well as in EXPECT_MASK macros.
Like with BitFields, we can express the integer 0b0000'0000'1100'0101 as a list of BitFieldMasks: {{0x0, 0x1, 1}, {0x1, 0x1, 0}, {0x2, 0x1, 1}, {0x3, 0x1, 0}, {0x4, 0xff, 12}}
In addition to showing how the integer is broken up, it also expresses the lengths of fields, so it is clear that 0x0 and 0x2 are one-bit fields. This also allows us to formally express that the fields 0x1 and 0x3 are unset.
In practice, this might use generated register constants, and look like {{FIELD_FOO_OFFSET, FIELD_FOO_MASK, 1}, ...}
