target/arm: Fix SCR RES1 handling
The FW and AW bits of SCR_EL3 are RES1 only in some contexts. Force them
to 1 only when there is no support for AArch32 at EL1 or above.

The reset value will be 0x30 only if the CPU is AArch64-only; if there
is support for AArch32 at EL1 or above, it will be reset to 0.

Also adds helper function isar_feature_aa64_aa32_el1 to check if AArch32
is supported at EL1 or above.
