WString Fix int64_t

Fixed int64_t String support. Resolves issue #7760.

Background:
sprintf on esp32 doesn't support "%lld" parameter.  It's possible to recompile the underlying libraries to add that option, but I have an easier solution.
This has already been solved in ESP8266 version of WString by replacing sprintf() with itoa/ltoa/lltoa.

This PR does the following:
Fixes integer print issues by replacing sprintf() with itoa/ltoa/lltoa
Moves concat(long long num), concat(unsigned long long num) location (match ESP8266)
Cleans up code formatting (matches ESP8266)

I think "Arduino as an ESP-IDF component" or just "As ESP-IDF component" instead of  "ESP-IDF as Component" is more correct way to name the link.

1. "ESP-IDF as Component" would imply that ESP-IDF is some sort of library for Arduino, which is (IMO) misleading, because it's true the other way around.
2. It's written as "Arduino as an ESP-IDF component" on the webpage it points to as well.

- Also I removed the capitalization from "Component" as I have not found a reason why is it capitalized.

Allow passing IP as connect method parameter in WiFiClientSecure and skip unnecessary host-ip conversions (#7643)

[ESP32: SDMMCFS::begin hardcodes the usage of slot 1, only check if the pins match slot 1 pins.]

setPins() was testing pins D1, D2 and D3 all against D1 ... fine in 1 pin mode when all are -1 not so much if you're trying to get 4 pin mode working.
I now see this function doesn't really do anything on the ESP32...accept now correctly checks that you are trying to use the slot 1 pins.

* Update WiFiClient.cpp

This change will allow specifying connect timeouts below 1 second. Without this change, if connect timeouts under 1 second are given, the connect defaults to 0ms and fails. 
This will also allow timeouts in fractions of seconds, e.g. 1500ms. Without this change, connect timeouts are truncated to full second increments.

* Make parameter timeout_ms clear

* Change connection timeout_ms name for clarity

Wrong name in definitions.

* Fixes BLE data printing

BLE data has no '\0' terminator, therefore it can't be printed as a regular C string.
This fix just prints the BLE data based on its length.

* Simplify printing to a single call

Heltec updated the I2C pins in https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/commit/b10f4bf85d13fd01be80dcdb0eb59e6a8c8ba19a

* Modified WiFiClient example to use thingspeak instead of non-functionig sparkfun

* Moved instructions to README

* Fixed spelling

* Added link to S3 datasheet
