jeanPerier 2d956d2d4e [flang] fix ICE with ignore_tkr(tk) character in explicit interface (#140885) ...

Some MPI libraries use character dummies + ignore(TKR) to allow passing
any kind of buffer.

This was meant to already be handled by #108168
However, when the library interface also had an argument requiring an
explicit interface, `builder.convertWithSemantics` was not allowed to properly deal
with the actual/dummy type mismatch and generated bad IR causing errors like:
`'fir.convert' op invalid type conversion'!fir.ref' / '!fir.boxchar\<1\>'`.

This restriction was artificial, lowering should just handle any cases
allowed by semantics. Just remove it.
