We were handling target-typed conditional and switch expressions wrong in a few cases, which caused a series of issues:

1. Lambdas underneath these contexts were never visited in nullable, so warnings in their bodies weren't reported.
2. Target-typed conditionals contributed to nullable inference of the thing they were getting their target-type from in the first place.

To fix this, I've made a couple of changes. First, we add a discrete BoundConversion node for the target-typed conditional conversion. This ensures that the standard "remove conversion, visit operand, redo conversion" practice we have throughout the nullable walker handles these constructs correctly. I also split up the conversion steps for these constructs: if the construct was target typed, we now save the states for each branch at the end of their respective VisitX methods, and then when we have a target-type with nullability in VisitConversion, we pull that info out and visit the nested contexts correctly. As part of this, I fixed a couple of other bugs:

1. VisitSwitchExpression was needlessly calling VisitConversion multiple times. This caused some warnings to be double-reported, which it now only reports once.
2. We were missing IConversionOperation nodes that should have been in the IOperation tree.
3. The behaviors for GetTypeInfo and GetConversion didn't match our usual handling of explicit vs implicit conversions.

Fixes #51403. Fixes #49735.
