eaac23fdd4 [NFC] Remove ASTExtInfo::assertIsFunctionType in favor of checkInvariants.
Invariants should be checked only when calling build(), not when the builder
itself is created.

29188e3fe7 [AST] Update equality for ExtInfo to take Clang types into account.
In the future, we will remove the UseClangFunctionTypes language option, but we
temporarily need the scaffolding for equality checks to be consistent in all
places.

f219e58ada [NFC] Refactor ExtInfo to use a builder-pattern based API.
Since the two ExtInfos share a common ClangTypeInfo, and C++ doesn't let us
forward declare nested classes, we need to hoist out AnyFunctionType::ExtInfo
and SILFunctionType::ExtInfo to the top-level.

We also add some convenience APIs on (AST|SIL)ExtInfo for frequently used
withXYZ methods. Note that all non-default construction still goes through the
builder's build() method.

We do not add any checks for invariants here; those will be added later.
