[Electron] Wire1 fixes

[avtolstoy]

Problem

Issue #1282.

• Wire1 on Electron does not work correctly.
• There are no Wire1 I2C tests

Solution

• Ensures that Wire and Wire1 on Electron cannot be enabled simultaneously, since they share the same peripheral
• wiring/no_fixture test added: WIRE_02_Wire_and_Wire1_cannot_be_enabled_simultaneously_on_Electron
• Correct HAL I2C interface id needs to passed when I2C1 interrupt handler is executed, depending on whether Wire or Wire1 is enabled.
• Wire::reset() implementation moved to HAL (HAL_I2C_Reset)
• i2c_master_slave and i2c_mcp23017 tests now accept USE_WIRE make argument that specifies which Wire interface should be used in tests (e.g. make PLATFORM=electron TEST=wiring/i2c_mcp23017 USE_WIRE=Wire1 clean all program-dfu)

Steps to Test

• wiring/no_fixture: WIRE_02_Wire_and_Wire1_cannot_be_enabled_simultaneously_on_Electron
• i2c_mcp23017
• i2c_master_slave/i2c_master and i2c_master_slave/i2c_slave
