Various warning fixes (#1812)

* Fixed -Wreserved-id-macro warnings from header include guards

* Removed all __int64 and LL suffix stuff now that C99 is minimum requirement

* Rename `H5FD_CTL__` to `H5FD_CTL_` to fix -Wreserved-id-macro warnings

Double underscore is reserved in C++ and this public header should be C++ compatible.

* Never define __STDC_FORMAT_MACROS anymore

Defining it causes a -Wreserved-id-macro.

Happily, according to the C++11 standard:

"The macros defined by <stdint> are provided unconditionally. In particular, the symbols __STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS (mentioned in C99 footnotes 219, 220, and 222) play no role in C++."

So looks like it's not necessary to define it with reasonably new toolchains.

* Fixed some -Wunused-macros warnings, removed dead code

* Fixed all -Wdouble-promotion warnings in C++ files

* Fixed remaining -Wsuggest-destructor-override warnings

* Committing clang-format changes
