  [clang][UBSan] Make sure that the implicit-conversion group is compatible with minimal runtime (#114865)

We are currently getting:

`clang: error: invalid argument '-fsanitize-minimal-runtime' not allowed
with '-fsanitize=implicit-conversion'`

when running

`-fsanitize=implicit-conversion -fsanitize-minimal-runtime`

because `implicit-conversion` now includes
`implicit-bitfield-conversion` which is not included in the `integer`
check. The `integer` check includes the `implicit-integer-conversion`
checks and is supported by the trapping option and because of that
compatible with the minimal runtime. It is thus reasonable to make
`implicit-bitfield-conversion` compatible with the minimal runtime.
