Detailed description

Bin

- Load exception information by default

Analysis

-  Make analyzing exception scopes the default
-  Analyze all exception sources as functions
-  Do not hack basic blocks flow to add try/catch information

Graph

- Add an edge pointing to the catch block for each basic block inside the try scope
-  Add configuration graph.trycatch to control if graphing the exception blocks is enabled

Problems

    8ff06e9 Is basically copy-pasted logic from block.c
    This can make graphs a lot noisier
    Cutter will have to implement its own version of the logic if it wants to copy rizin in showing the connection between the blocks and its catch blocks
    I didn't add tests yet

Test plan

Open bins\pe\microsoft_seh_tests\x64\xcpt4.exe for example
Optional: idp to load debug info for binary
aaa
Optional: .iw to show try catch scopes as flags
s main
Enter visual graph mode, make sure all edges, lines are painted correctly, and that there area now new edges pointing each basic block to its catch block if it is inside a try scope

Open file from rizinorg#2247
aaa
s main
Enter visual graph mode, make sure issue is fixed
