Allow fir.rebox input and output element type to differ for characters
if:
- Any of the character type is dynamic. Fortran allows making pointer
assignments between deferred and constant lengths entities, making this
case useful (if the input length is dynamic and the output length constant,
it is a user requirement that the length matches at runtime. There is no
option to check this at runtime, but it could be added as an option to
fir.rebox codegen later if desired).
- Or, there is a slice in the fir.rebox (the fir.rebox can implement a
substring view, hence the constant output and input lengths).
This is only a verifier constraint change, the fir.rebox codegen is not
impacted and already support those cases.
Add related FIR parsing, error, and codegen tests.

This option is added in both `flang-new` (the compiler driver) and
`flang-new -fc1` (the frontend driver). The semantics are consistent
with `clang` and `clang -cc1`.
As Flang does not run any LLVM passes when invoked with `-emit-llvm`
(i.e. `flang-new -S -emit-llvm <file>`), the tests use
`-S`/`-c`/`-emit-obj` instead. These options require an LLVM backend to
be run by the driver to generate the output (this makese `-mllvm`
relevant here).

`semantics::IsSaved()` was not applying -Msave/-fno-automatic for main programs.
This caused issues since lowering relies on it to allocate static
variables. This did not match nvfortran/gfortran behaviors where
-fno-automatic/-Msave control the static allocation of scalars in
main programs.
Some program may rely on main program scalars to be statically allocated in
bss (and therefore initialized to zero) with -Msave/-fno-automatic
flags.

There is currently an awkwardly complex set of rules for how a
parser/printer is generated for AttrDef/TypeDef. It can change depending on if a
mnemonic was specified, if there are parameters, if using the assemblyFormat, if
individual parser/printer code blocks were specified, etc. This commit refactors
this to make what the attribute/type wants more explicit, and to better align
with how formats are specified for operations.
Firstly, the parser/printer code blocks are removed in favor of a
`hasCustomAssemblyFormat` bit field. This aligns with the operation format
specification (and is nice to remove code blocks from ODS).
This commit also adds a requirement to explicitly set `assemblyFormat` or
`hasCustomAssemblyFormat` when the mnemonic is set and the attr/type
has no parameters. This removes the weird implicit matrix of behavior,
and also encourages the author to make a conscious choice of either C++
or declarative format instead of implicitly opting them into the C++
format (we should be pushing towards declarative when possible).

https://reviews.llvm.org/D120568 broke builds that set
both `LLVM_BUILD_LLVM_DYLIB` and `LLVM_LINK_LLVM_DYLIB`. This patch
fixes that.
The build failure was caused by the fact that some LLVM libraries (which
are also LLVM components) were listed directly as link-time dependencies
instead of using `LINK_COMPONENTS` in CMake files. This lead to a linker
invocation like this (simplified version to demonstrate the problem):
```
ld lib/libLLVM.so lib/libLLVMAnalysis.a lib/libLLVMTarget.a
```
That's problematic and unnecessary because `libLLVM.so` incorporates
`libLLVMAnalysis` and `libLLVMTarget`. A correct invocation would look
like this (`LLVM_LINK_LLVM_DYLIB` _is not_ set):
```
ld lib/libLLVMAnalysis.a lib/libLLVMTarget.a
```
or this (`LLVM_LINK_LLVM_DYLIB` _is_ set):
```
ld lib/libLLVM.so
```
