[C-libcurl] Change baseName to name to escape the field name of struct

[ityuhui]

Change "baseName" to "name" to escape the field name of struct when it includes C programming language keyword

As described in Issue 4700
I found "baseName" cannot be escaped for the keyword, only "name" can.
I checked this part in cpp-rest-sdk-client and cpp-qt5-client, they do not use "baseName", but use "name". So I have made these code change.

PR checklist

• Read the contribution guidelines.
• If contributing template-only or documentation-only changes which will change sample output, build the project before.
• Run the shell script(s) under ./bin/ (or Windows batch scripts under.\bin\windows) to update Petstore samples related to your fix. This is important, as CI jobs will verify all generator outputs of your HEAD commit, and these must match the expectations made by your contribution. You only need to run ./bin/{LANG}-petstore.sh, ./bin/openapi3/{LANG}-petstore.sh if updating the code or mustache templates for a language ({LANG}) (e.g. php, ruby, python, etc).
• File the PR against the master: master, 4.3.x, 5.0.x. Default: master.
• Copy the technical committee to review the pull request if your PR is targeting a particular programming language.

Right, let's go with name instead of baseName but we may need to provide an option to let people choose or we need to implement better serialization between property name in the C client (e.g. created_by) and the JSON key name (e.g. created-by).
